<p>The main problem is that you have expl-syntax mid document which means that the <code>memos/.....def</code> files get written with mixed syntax, ends of lines are just taken as spaces so blank lines (and the end of file) do not generate <code>\par</code> tokens and the argument matching fails. If you make document-level aliases for the commands o you do not need <code>\explSyntaxOn</code> mid-document the runaway error is avoided</p> <pre><code>\DocumentMetadata{lang=en-GB,tagging=on,pdfversion=2.0,pdfstandard=UA-2,} \documentclass{article} \tagpdfsetup{math/mathml/luamml/load=false,} \title{Title} \usepackage{memoize} \ExplSyntaxOn \makeatletter \cs_new_eq:NN \__mmzx_property_ref_orig:nn \property_ref:nn \cs_new_eq:NN \__mmzx_property_record_orig:nn \property_record:nn \cs_generate_variant:Nn \__mmzx_property_ref_orig:nn { ee } \cs_generate_variant:Nn \__mmzx_property_record_orig:nn { ee } \tl_new:N \g__mmzx_label_tl \tl_new:N \g__mmzx_rec_tl \cs_new_nopar:Npn \__mmzx_auto_property_ref_noopt:nn #1#2 { \property_if_recorded:nnTF { #1 } { #2 } { \__mmzx_auto_property_ref:nn { #1 } { #2 } } { \mmzAbort } \AdviceOriginal {#1}{#2} } \cs_new_nopar:Npn \__mmzx_auto_property_ref_opt:w [#1]#2#3 { \property_if_recorded:nnTF { #2 } { #3 } { \__mmzx_auto_property_ref:nn { #2 } { #3 } } { \mmzAbort } \AdviceOriginal [#1] {#2}{#3} } \cs_new_nopar:Npn \__mmzx_auto_property_ref:nn #1#2 { % only running if memoizing ... \gtoksapp\mmzContextExtra{ \detokenize { \property_ref:nn } {#1}{#2} ~ -&gt; ~ \csname __mmzx_property_ref_orig:ee \endcsname {#1}{#2}, } } \cs_new_nopar:Npn \__mmzx_auto_property_record:nn #1#2 { \tl_gset:Ne \g__mmzx_label_tl { #1 } \tl_gclear:N \g__mmzx_rec_tl \group_begin: \cs_set_eq:NN \property_ref:nn \__mmzx_property_ref_orig:nn \clist_map_function:nN {#2} \__mmzx_auto_property_record_aux:n \group_end: \tl_if_empty:NF \g__mmzx_rec_tl { \tl_gput_right:NV \g__mmzx_rec_tl \c_right_brace_str \tl_gput_left:NV \g__mmzx_rec_tl \c_left_brace_str \tl_gput_left:Nn\g__mmzx_rec_tl { \mmzxRecProperty {#1} } } \exp_args:NNV \gtoksapp\mmzCCMemo \g__mmzx_rec_tl } \cs_new_nopar:Npn \__mmzx_auto_property_record_aux:n #1 { \exp_args:NV \property_if_recorded:nnTF \g__mmzx_label_tl { #1 } { \tl_gput_right:Nn \g__mmzx_rec_tl {{#1}} \tl_gput_right:Ne \g__mmzx_rec_tl { \c_left_brace_str \property_ref:ee {\g__mmzx_label_tl}{#1} \c_right_brace_str } }{ \mmzAbort } } \cs_new_nopar:Npn \__mmzx_property_record:nn #1#2 { \protected@write\@auxout {} { \string \new@label@record {#1}{#2} } } \cs_new_eq:NN \mmzxRecProperty \__mmzx_property_record:nn \def\mmzx@auto@ref@property { \@ifnextchar[\__mmzx_auto_property_ref_opt:w \__mmzx_auto_property_ref_noopt:nn } \def\mmzx@auto@rec@property#1#2 { \__mmzx_auto_property_record:nn {#1}{#2} \__mmzx_property_record_orig:nn {#1}{#2} % \AdviceOriginal{#1}{#2} } \mmzset{% prefix=memos/, include ~ context ~ in ~ ccmemo, auto/ref ~ property/.style={run ~ if ~ memoizing,outer ~ handler=\mmzx@auto@ref@property,}, auto/rec ~ property/.style={run ~ if ~ memoizing,outer ~ handler=\mmzx@auto@rec@property,}, auto ~ csname={property_record:nn}{rec ~ property,}, auto ~ csname={property_ref:nn}{ref ~ property,}, } \makeatother \let\propref\property_ref:nn \let\proprec\property_record:nn \ExplSyntaxOff \newcounter{my} \begin{document} \parindent=0pt \begin{memoize} abc \RefProperty{A}{page} def \RefProperty{A}{abspage} xyz \propref {B}{page} uvw \propref {B}{abspage} rst \ref{my} \end{memoize} \mmzxRecProperty{p}{{page}{2}{abspage}{2}} \newpage \begin{memoize} ghi jkl \RecordProperties{A}{page,abspage} \proprec {B} {page,abspage} \refstepcounter{my}\label{my} \end{memoize} \end{document} </code></pre>

in relation to the last one then (other than luatex) you can not do that, tex uses fixed memory allocation so within limits you can increase the size of the arrays allocated, but if you do then tex will always use that amount. The units depend on the parameter, some are numbers (characters per line, sizes of arrays, etc) some are strings (default paths) some are special codes like `p (for read/write security settings

your last link is 10 years old so apart from Ulrike&#39;s updated answer misses relevant information on making tagged pdf from latex, start from <a href="https://latex3.github.io/tagging-project/" rel="nofollow noreferrer">latex3.github.io/tagging-project</a>

unrelated to your question but avoid <code>\usepackage{xunicode}\usepackage{xltxtra}</code> in xetex and don&#39;t use <code>\usepackage[utf8]{inputenc}</code> also you are missing a lot of <code>%</code> at ends of lines

also even if you use a tabular layout you should never use <code>\begin{table}[h]</code> here it makes no sense to float that table.

it looks like a standard table to me, i don&#39;t understand your comment &quot;because there is a table border, the length of the text inside it is not the same as the text area of the document.&quot; the comment is true but why is that a problem? You know the width of your border so know the necessary table width

everything that you could get from ctan is already in the tex distributions eg the tex doc is <code>&#47;usr&#47;local&#47;texlive&#47;2025&#47;texmf-dist&#47;doc&#47;metapost&#47;mptrees&#47;mptr&zwnj;&#8203;ees-doc.tex</code> in texlive and will be somewhere similar in miktex

where have you got that code from? neither <code>\mplibforcehmode</code> nor <code>exampleblock</code> are mentioned in the mptrees manual.

&quot;I have downloaded the mptrees package&#39;s ZIP file &quot; mptrees is in texlive and miktex, you shouldn&#39;t need anything from ctan

If your preamble only has <code>\usepackage{unicode-math} \setmathfont{texgyrepagella-math.otf}</code> then only math is changed and all text is whatever it was. If you get errors you should ask a new question with an example that makes an error

don&#39;t mix legacy font packages with xetex or luatex (and never use <code>\usepackage[utf8]{inputenc}</code> all it does in xetex is issue a warning that it should not be used. ) Your <code>\usepackage{pxfonts}</code> has reset all the fonts undoing all the settings you have previously. remove that and <code>amssymb</code> and if you want palatino math add <code>\usepackage{unicode-math} \setmathfont{texgyrepagella-math.otf}</code>

<code>\ifthenelse</code> makes <code>\pageref</code> testable (and makes it 0 on the first run rather than make a warning) for this reason. The testing with <code>\ifodd</code> is not false it is just that you need to be careful when you test. the page number changes throughout the document and the value when you do the test is odd or even but that may not be what you meant to test for. For example if you write a long 5 page paragraph, the page number does not change until after the paragraph is broken in to lines and the lines broken in to pages. So when all macros are expanded the page number is 1 and <code>\ifodd</code> is true.
