[xsl] Need an efficient function to determine if two XML trees are the same (same markup, same values)

["Costello, Roger L." <costello@xxxxxxxxx>]

Hi Folks,

I need an efficient XSLT 2.0 function that, given two XML trees, it returns
true if they are the same, false otherwise.

By "they are the same" I mean the trees have the same elements and attributes,
with the same values.

Do you have an efficient function that does this?
