But the intro to the DTD says that "only constructs that have XLink-defined
meaning are allowed." What's the XLink-defined meaning of a simple-type
element with no href?

Is the DTD trying to allow only "traversable" constructs? The comment below
the location element seems to imply this--thus the reason for requiring href
and label.

Curiously, though, the label attribute is not required on resource. Are
inline resources considered automatically traversable? Without a label, I
don't see that it's possible to refer to a resource from an arc-type
element.

I understand that the DTD is non-normative but I'm trying to understand what
an XLink-aware processor should be reporting to an application. An XLink
infoset would be really nice.
