Re: [xsl] the document() in IE

> Do you happen to know whether this holds for a variable or parameter? 
variables are bound to values, and by the time that it's passed to a
function such as document() it shouldn't matter whether the value was
passed to the function as a variable reference or any other kind of
expression.

Note however the difference between
<xsl:variable name="href" select="path/to/href"/>
and the form that you often see  beginners use:
<xsl:variable name="href">
  <xsl:value-of  select="path/to/href"/>
</xsl:variable>

With the first form, $href is an element node with base URI depending on
the document that contains the node, with the second form, $href is a
rtf (in xslt 1) and so will act as a string in document() with uri resolution being
against the base uri of the stylesheet. In XSLT2 $href will be a
document node, again with base URI being that of the stylesheet.

yes, but that's the same as 

document(string('path'))

usually when there are problems with uri resolution in xslt1 (I must say
I've not really done this much in client side stylesheets) its because
the base uri is not as expected, or not set at all. If the XSLt engine
is reading a document directly then it's fairly clear what the base URI
should be, but if the document (or the stylesheet) has previously been
read into a DOM of some sort, perhaps manipulated with DOM scripting,
and then passed as an in-memory tree to the XSLT processor, then the
XSLT REC gives you noi guidance at all on what the base URI of the nodes
will be, it is all completely implementation defined.
