Description

I'm creating this jira issue, to track implementation of XPath 3.1 built-in math functions within namespace http://www.w3.org/2005/xpath-functions/math.

XPath 3.1 built-in functions namespace http://www.w3.org/2005/xpath-functions/math, has maths trigonometric and exponential functions. The XPath functions available within this namespace, must be used by qualifying the function name with an XML namespace bound to the namespace name http://www.w3.org/2005/xpath-functions/math (the commonly used XML namespace prefix for this namespace name is "math", as suggested by XPath 3.1 spec).

I've written little bit of code for this, that has been committed to XalanJ dev repos's branch xalan-j_xslt3.0. Few related working test cases for these implementation aspects, have been committed as well to the same XalanJ dev repos's branch.
