Not a standard, but you might consider

   ftp://ds.internic.net/internet-drafts/draft-masinter-url-data-03.txt

which expires tomorrow.  I don't know whether the author expects to
update it.  It defines a data URL like

  data:[<mediatype>][;base64],<data>

in which the payload is encoded in base64 and the mediatype is a MIME
type.  It's SGML/XML-safe.
