**NAME**

libexslt - extension library for XSLT
**DESCRIPTION**

The libexslt library is used to provide extensions to XSLT functions. These extensions come from the EXSLT project (http://www.exslt.org/)
**CALLING**

To make use of these functions XSLT, these need to be declared with the proper name space
**SUPPORTED FUNCTIONS**

COMMON
Namespace: http://exslt.org/common
