Any xsd:import fixes lately?

Hi,

(I tried to seach for info in the archives before posting
this, but it seems
there are som problems with the search indexes...)

I'm using xmlstarlet, an xml command line tool which I
understand is based
on libxml2.

Including the follwing reference in a schema makes
xmlstarlet hang
(presumably somewhere within libxml2) when I use the schema
to validate an
xml document:
<xsd:import namespace="http://www.w3.or
g/XML/1998/namespace"
schemaLocation="http://www.w3.org/2001
/xml.xsd"/>

If I do not import the external schema (and remove related
elements in the
target xml document) the validation works fine.

The latest build of xmlstarlet dates back to March 2003, and
I'm tempted to
get the source (including the libxml2 source on which its
based) by CVS and
build a new version myself. Not being fluent in these
things, it would take
me a while.

So the question before digging into it is: Is it probable
that this problem
is caused by an outdated version of libxml, and is there a
chance that it
has been fixed by now?

Kind regards,
Svenn-Ivar

  grab the latest libxml2 (2.6.26) on xmlsoft.org,
recompile, and try your
schemas and instance with xmllint --schema . If it fails
report the full
schemas , if it doesnt fail it's due to an older version.
