OpenFormula?

I'm curious if for a library of xslt math functions, that users will be
presented with a formula signature, in XML, that they invoke a function
name, followed by data in a form for application of the formula. Yes?

I ask because Calc in the LibreOffice project has implemented a number
of the formulas in OpenFormula and if that engine could be invoked from
XSLT/XQuery, you would get the implementation for free while providing
users with an XML syntax.
