Using XmlSecureResolver.CreateEvidenceForUrl?

[redevries]

I am having trouble getting a transformation to work. Basic
transformation
works locally - i.e. if I have the XSL on a local system it all works
as it
should. My XSLT uses references another external XML document.

When I move the XSLT to a UNC it stops pulling in nodes from an
external
XML, using a 'document' reference in the XSLT. The 1.1 framework seems
to
deal with this in a slightly different (more secure) way, which is
described
here....

http://msdn.microsoft.com/library/de...tprocessor.asp

So, here is what I did:

Dim evidence As Security.Policy.Evidence =
XmlSecureResolver.CreateEvidenceForUrl("\\someserv er\d$\WWWROOT\Portal\sp2\X
SL\")
xslt.Load(New
XmlTextReader("\\someserver\d$\WWWROOT\Portal\sp2\ XSL\newsletter_html.xsl"),
New XmlUrlResolver, evidence)

When I do the transform, it actually does work, but it doesn't pull in
the
external reference. So, my guess on reading the first link is that I
need to
make a policy change somewhere - but I have no idea what or where.

Any insights much appreciated!

Above only helps to resolve URLs during loading XSLT stylesheet
(xsl:include/xsl:import).
document() function is called later - at transformation time, so you
have to proivide similar resolver and evidence to Transform() method too.
