Yes, XeTeX supports only a subset of the hyperref functionality at 
present (bookmarks and links, basically; and it's very possible that 
not all link types will work). It doesn't support adding document 
metadata.

If you use the hyperref functionality (with the dvipdfm option), the 
PDF that XeTeX generates via Quartz is post-processed using a Perl 
library (PDF::Reuse) to add bookmarks and links; a side-effect of this 
process is that the original metadata from Quartz is lost and the PDF 
version updated.
