In the conformance section, it says:

	... the declared type of attribute values is in principle
	only available in documents which have been validated.

Depends which principle you follow, but the principle isn't the
point I think.  The point is that only processors that read
external parameter entities will necessarily know those types.

That is, validation is irrelevant -- it's whether the external
parameter entity is read.  Any processor that reads external
PEs can support such checks ... it's comparable to the way the
XML spec requires non-CDATA attributes to be normalized, even
for nonvalidating processors.

p.s. I'm glad this seems to be stabilizing!
