Use https://www.w3.org/TR/xslt-10/#function-function-available to check
from within XSLT if a certain function is available.

Most XSLT 1.0 processors support exsl:node-set in the namespace
http://exslt.org/common, with the exception of older Microsoft products
like MSXML or XslTransform which instead support a node-set extension
function in a Microsoft namespace.

Not sure about Xalan, I think the Java product has support for a Xalan
specific namespace as well as the EXSLT namespace.
