Does anyone still use the EXSLT extension library methods?
Many of the Math and Sets functions have been broken since .NET 4.0 (as Microsoft moved around a few internal classes to new namespaces).
Since this has largely gone unnoticed - as in there hasn't been any bugs raised and zero complaining on the forum - should we look to obsolete (then remove) the EXSLT classes from the core?
My suggestion would be to move EXSLT to a separate package download, so that they can be re-enabled for those who do still use the other methods (e.g. Dates, RegEx, Strings)
