As far as I remember from a talk at TUG 2015, the packages used to
produce PDF/A using pdftex were extended to work with LuaTeX (perhaps
using newer versions of the package) and one difficulty they faced
with XeTeX was the lack of a way to compute MD5 sums.  Now IIRC a
primitive was very recently added to XeTeX for MD5 sums.  So perhaps
it wouldn't be too much work to port the package to XeTeX.

I really don't know tbh,
