+% \subsection{Advanced metadata detection}
+%
+% \pkgname{hyperxmp} strives to be as convenient and user-friendly as
+% possible. To that end, we try to automatically detect as much
+% metadata as possible. The author can of course augment or override
+% autodetected metadata by explicitly providing values to
+% \cs{hypersetup}, but the hope is that we can save the author some
+% effort in many cases.
+%
+% In this section, we identify additional metadata we can use. Most of
+% the functionality is class- or package-specific. For example, we
+% check for phone numbers provided to the \Koma\ letter classes via
+% |\setkomavar{fromphone}{|\dots|}| and/or
+% |\setkomavar{frommobilephone}{|\dots|}|, street addresses provided to
+% the \ACMclass\ article class via \cs{affiliation}, and languages
+% the \pkgname{polyglossia} package is instructed to load via
+% \cs{setdefaultlanguage} and \cs{setotherlanguage}.

+% \begin{macro}{\hyxmp@write@pdflang}
+% Here's a conundrum: \pkgname{babel} doesn't provide access to
+% information on the document's main language until after the
+% |\begin{document}|. However, \pkgname{hyperref} allows
+% \optname{pdflang} to be set only \emph{before} the |\begin{document}|.
+% So what do we do?
+%
+% Note that the underlying \cs{@pdflang} macro serves two purposes:
+% \pkgname{hyperref} uses it to set the \pdfterm{Lang} entry in the
+% \acro{PDF} document catalog, and \pkgname{hyperxmp} uses it as the
+% default metadata language. The latter is used in \xmpprop{dc:title}
+% and other \acro{XMP} properties that can include per-language
+% variants. We set \cs{@pdflang} once we have the main-language
+% information from \pkgname{babel}. As this is too late for
+% \pkgname{hyperref}, we bypass \pkgname{hyperref} and manually write
+% the \pdfterm{Lang} key into the document catalog. This is a bit
+% kludgy, but we do leverage as much of \pkgname{hyperref}'s
+% infrastructure as possible to increase \cs{hyxmp@write@pdflang}'s
+% robustness.
