With or without schemas, you can tag elements as containing base-64 encodings of any MIME type you want. But there has to be an encoding, not raw binary bits. > So... is there any public information about XML-Schema? Any idea if one or > more binary formats is called out as a datatype within it? You can read the various W3C Notes: XML-Data, DCD, SOX, DDML. None of them tolerate raw binary. Several provide a datatype tag for base-64-encoded octets. -- John Cowan http://www.ccil.org/~cowan cowan@c... You tollerday donsk? N. You tolkatiff scowegian? Nn. You spigotty anglease? Nnn.
