Result tree fragment was read-only

Type-system based on XML Schema

More types: date and time.

Numeric matches now the decimal, integer, double or float types

Types are "optional"

Basic XSLT processor: almost the same as XSLT 1.0 with some additionnal built-in types

Schema-aware processor:

All built-in types defined in XML Schema (plus few more)

Template can be typed and validated at runtime
