As far as I know, there are no XSLT processors that will access and

2.0, but for now if you want to set a default for an attribute you
should use a DTD.

Or it's quite commonly possible to write the XSLT to provide its own default. (Only reason I can think of not to is a multiple-DTD/single-stylesheet architecture, which would be far less ordinary than the other way around.) This also has the advantage of loosening the document-DTD/schema coupling for processing (often a good thing).

As I understand it, the notion that a stylesheet or other process will provide its own defaults, is underneath the otherwise mystifying name of the #IMPLIED keyword in SGML/XML DTDs. That is, the attribute is optional in the instance, so its value may be taken as "implied" (because the processor will know what it should be, or doesn't care).
