Loading order of hyperref and hyperxmp should be reversed

[iincer]

Summary

The current version of acmart raises an error saying that hyperxml must be loaded before hyperxmp.

Reason

hyperxmp v5.12 (released on 9/10/23) introduced the following requirement:

New in v5.12 hyperref must be loaded before hyperxmp.
This is because recent changes in hyperref and the LATEX
kernel prevent hyperxmp from hooking into hyperref’s internals
if hyperref is loaded first.

The following code shows how acmart loads hyperref and hyperxmp:

acmart/acmart.dtx

Lines 3474 to 3489 in ec4b7b0

	\RequirePackage{hyperxmp}
	% \end{macrocode}
	%
	%
	% And now, |hyperref|
	% \changes{v1.28}{2017/01/07}{Got rid of warnings in pdf keywords}
	% \changes{v1.46}{2017/08/25}{Delayed hypersetup since journal options
	% may change screen mode}
	% \changes{v1.55}{2018/10/20}{Now we use purple color for links}
	% \changes{v1.58}{2019/26/01}{Suppressed \cs{addtocounter} in pdf
	% subject}
	% \changes{1.85}{2022/05/08}{Added: acmengage}
	% \begin{macrocode}
	\let\@footnotemark@nolink\@footnotemark
	\let\@footnotetext@nolink\@footnotetext
	\RequirePackage[bookmarksnumbered,unicode]{hyperref}

Solution

Reverse the loading order of hyperref and hyperxmp.
