[xsl] Question for a code example of <xsl:evaluate> in which the target expression calls a user-defined xsl:function

["Dimitre Novatchev dnovatchev@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I need to call an existing xsl:function from within the xpath
(target-expression ) attribute of <xsl:evaluate>.

1. Is this possible / allowed? From reading the W3C XSLT 3.0 Spec it seems
so -- https://www.w3.org/TR/xslt-30/#dynamic-xpath  has a bullet in the
list of available function signatures, saying :

"All user-defined functions present in the containing package provided
their visibility is not hidden or private;"

However, my attempts to call such an existing xsl:function from within the
target-expression were not successful.

2. Could someone provide a working code example of doing this?

Dr. Kay ?
