Re: [xsl] How do I pass the mode as a string?

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

While this is not allowed in XSLT, one can accomplish the passing functions
as parameters.

For XSLT 1.0, 2.0 see the FXSL library.

The XSLT 3.0 / XPath 3.0 and 3.1 standards support higher order functions.
