Thanks for pointing on this URL, I feel relieved :) ...
However, I think it sucks or at least that this is not my understanding
of the meaning of xml:base and simple XLinks.
XML base is about providing a base URI for relative URIs:
"XLink normatively references XML Base for interpretation of relative
URI references in xlink:href attributes."
But the source of a xlink simple link is local:
"[Definition: A simple link is a link that associates exactly two
resources, one local and one remote, with an arc going from the former
to the latter. Thus, a simple link is always an outbound link.]"
And local resources are not addressed by URIs (relative or not):
"[Definition: A local resource is an XML element that participates in a
link by virtue of having as its parent, or being itself, a linking
element]. [Definition: Any resource or resource portion that
participates in a link by virtue of being addressed with a URI reference
is considered a remote resource, even if it is in the same XML document
as the link, or even inside the same linking element.] Put another way,
a local resource is specified "by value," and a remote resource is
specified "by reference.""
For an application following the semantics defined in those two recs,
the link seems to be between a node in the
http://www.openhealth.org/RDDL/ document and the document
http://www.rddl.org/natures whatever the value of xml:base might be.
The "right" way to do it would be to use extended links, but RDDL would
loose all its simplicity and I fear that we are stuck with this nasty hack!
Thanks
Eric
