fleld name with comma ","

[lbonco]

Hi,

if I try the following test:

\RequirePackage{pdfmanagement-testphase}
\DeclareDocumentMetadata{uncompress,
    lang=it-IT,
    pdfversion=1.5,
    testphase={phase-III,math,title,table,firstaid}
} 
\RequirePackage{expl3}


\documentclass[12pt]{article}
\usepackage{l3pdffield-testphase}
\begin{document}
\ExplSyntaxOn
\pdffield_textfield:n {name={test,2}}
\ExplSyntaxOff
\end{document}

I get:

! LaTeX Error: The key 'pdffield/2)' is unknown and is being ignored.

For immediate help type H <return>.
 ...                                              
                                                  
l.14 \pdffield_textfield:n {name={test,2}}
                                        
? 
! Emergency stop.
 ...                                              
                                                  
l.14 \pdffield_textfield:n {name={test,2}}

I think that the problem is in: l3pdffield-textfield.dtx:516, the value of the "parent" key should be between braces:

    \keys_set:nn {pdffield}{parent={@@/textfield/#1}}

Thanks,
Luca
