xml:base not used with xsi:schemaLocation?
Hi,
I'm trying to validate a XML document that contains a schema reference
with xsi:schemaLocation (a relative path). I also have xml:base="../../"
set. Unfortunately, the schema files are not found. When I change the
path of the schema in schemaLocation (prepend ../../ from the xml:base)
the schema file is found.
For xinclude (which I also use) xml:base works.
Is this a xerces limitation or is xml:base not supported for the
schemaLocation attribute?

Seems that this already has been discussed, results at [1]:

Unfortunately I was not able to find information on how to absolutize
relative URIs in the most recent XML Schema 1.1 WD. But still, adding
support for xml:base seems to be in line with the ideas of the WG.

The XML Schema WG does have a public comments mailing list [1] and Bugzilla
tracker [2]. It wouldn't hurt to raise this issue there. Discussion with
the WG might result in improvements to the spec.

I did at
http://issues.apache.org/jira/browse/XERCESJ-1366
I understand that Xerces is doing nothing wrong here and I don't know
what the XML Schema Working Group thinks about it, so there might be
some more discussion with the authors of XML Schema needed (from what
I've seen it's not mentioned in the XML Schema 1.1 WD either).

XInclude was developed much later and actually does reference xml:base so
was clearer that we were supposed to do something there. If you're
interested in seeing this apply to schema processing too, you should open a
feature request [1].

Thanks for your reponse. I already expected it to be that way :( Still,
the current behavior is confusing, as xml:base is considered for
XInclude but not for Schema inclusion, i.e. the same relative path
inside a XML document will resolve to two different locations when using
xml:base.

Hi Philipp,
The XML Schema specification [1] places no requirements on processors to
support xml:base. It's not mentioned anywhere in the spec. So while Xerces
doesn't support it in its schema processor I wouldn't necessarily call it a
limitation.
Thanks.
