 %    \item[\texttt{pdfstandard}] Choice key to set the pdf standard.
 %      Currently |A-1b|, |A-2a|, |A-2b|, |A-2u|, |A-3a|, |A-3b|, |A-3u| and |A-4|
-%      are accepted as
-%      values. The casing is irrelevant, |a-1b| works too.
-%      The underlying code to ensure the requirements (as far as they
-%      can be ensured) is still incomplete, but a color profile is included and the
-%      \texttt{/OutputIntent} is set. The |u| variants for example do not force unicode,
-%      but they will pass the information to hyperref and hyperxmp. The |a| variants
+%      are accepted as values for A-standards. The casing is irrelevant, |a-1b| works too.
+%      Note that using these
+%      key doesn't mean that the document actually follows the standard. \LaTeX{}
+%      can neither ensure nor check all requirements of a standard, and not everything
+%      it can do theoretically has already been implemented.
+%      For A-standard a color profile is included and the
+%      \texttt{/OutputIntent} is set and javascript action in hyperref are suppressed.
+%      The |u| variants do not force unicode,
+%      but they will pass the information to hyperref. The |a| variants
 %      do \emph{not} enforce (or even test) a tagged pdf yet.
 %      More information can be found in the documentation
 %      of \pkg{l3pdfmeta}.
 %
+%      Starting with version 0.95s it is also possible to use the values
+%      |X-4|, |X-4p|, |X-5g|, |X-5n|, |X-5pg|, |X-6|, |X-6n|, |X-6p|, |UA-1| for
+%      a PDF/X and PDF/UA standard. These keys set \emph{only} the relevant
+%      XMP-metadata.
+%
+%      |pdfstandard| can be used more than once to set overlapping standards, e.g:\\
+%      |pdfstandard=A-2b,pdfstandard=X-4,pdfstandard=UA-1|
+%
 %    \item[\texttt{colorprofiles}] This allows to load icc-colorprofiles. Details
 %       are described in the documentation of \pkg{l3pdfmeta}.
