[ZPT] Is PageTemplates doing xhtml conversion? Should it?

[Phil Harris]

Since XHTML is an application of XML it should be case-sensitive.  At the
moment it's just a recommendation that you put *all* tags and attributes
lower case, but that may change, I'd say that if you're not writing in XHTML
at the moment, then you will be pretty soon.
