Schema-aware processing with XSLT 2.0

With the release of version 2.0, XSLT now allows you to design your stylesheets to
be schema-aware. A schema-aware XSLT system offers many benefits, including the
ability to validate input trees prior to the XSLT transformation to ensure that the
XSLT stylesheet only processes valid input, as well as the ability to validate output trees to ensure that the XSLT transformation is producing the valid XML output. You are also able to specify data types for variables, for input parameters for user-defined functions and templates, and for return values from the functions. In this article, learn more about the concept of schema-aware facilities and follow some examples that illustrate the benefits.
