There are two problems with viewing XML documents with SGML viewers:

1. XML requires a special SGML declaration. Not all SGML viewers support
alterntative SGML declarations (Panorama and all Synex Viewport-based
viewers do not, for example).

2. Unless an SGML viewer supports the WebSGML TC, it may not recognize a
well-formed XML document as also being an SGML document.

Because PIs in XML end with "?>" instead of the default ">" of SGML, the
XML declaration PI may be enough to cause some SGML viewers to reject the
document entirely.

Having said all this, I would be very supprised if there are any
actively-developed SGML viewers that don't support XML within the next 6 to
12 months. It's not like it's hard to do.
