Say you pass:

<foo>1</foo>

as a parameter to the stylesheet with a param definition of:

<xsl:param name="foo" as="document-node()"/>

If it's passed a string:

"<foo>1</foo>"

you'll get an error, but if its passed as a document node then it will be fine.

The problem is constructing the document in the host language and then
passing it in - I've always found it to be a pain and it does limit
how your transform can be run (not from the command line for example)
so instead I would always pass in strings and manage the process
myself:

<xsl:param name="foo-str" as="xs:string"/>
<xsl:variable name="foo" select="saxon:parse($foo-str)" as="document-node()"/>
