HI,

Using C++ I do add a document as parameter and refer to it in XSL as:

<xslt:param name="data"/>
...
<xslt:value-of select="$data//field[ @id = current()/subform[ @id = 'request'
]/@subjectid ]"/>

Don't know whether node-set sis expected or a single node (doc-root)

it than that. There was an infamous erratum to the XSLT 1.0 specification than
said disable-output-escaping was "sticky", i.e.

this property of the character would be remembered when the time came to
serialize. However, the property won't affect a test like
(contains($tradingPartner, '>')), and it probably won't be copied when you
copy the variable to another variable. And this erratum was effectively
rescinded in XSLT 2.0).
