Transforms the passed in XML into the required output (usually
HTML) using the passed in XSLT. Both the XML and XSLT strings
should be well-formed. Returns the output as a string.
transformObject and REQUEST params may be used to acquire Zope
content such as XSLT parameters and URN namespaces, if
required.
Catches any Pyana specific exceptions and raises an Exception
