The href attribute of xsl:result document is an attribute value
template, not an XPath expression. If you write href="$x" that means you
want the URI to be "$x", if you write href="{$x}" that means you want
the URI to be whatever the value of variable x is.
If the value of the href attribute is a relative URI, it's interpreted
relative to the base URI of the principal output document. This is known
when you use the -o option on the Saxon command line, but is unknown if
you send the result to standard output.

Subject: [xsl] using {} brackets with xsl:result-document
href (Saxon 7.4)
Can someone please explain why I need to use {} bracket in
the href of
xsl:results-document?
I'm familiar with using {} as a shortcut for writing values
into output
attributes but I'm not sure why I can't do something like:
<xsl:result-document href="string($vFilePath) ...
Saxon (7.4) gives me the following error:
"the system identifier of the principal output file is unknown"
No doubt I totally misunderstand the {} :-)
Below are some examples of xsk:result-document which have confused me.
Thanks for your help.
cheers
