XSLT, 2nd Edition

Defining Datatypes

Some of the elements and attributes we’ve created to this point use the built-in XML Schema datatypes. The ability to define our own types is a powerful feature of the language. Custom datatypes are the feature most directly related to XSLT. With a schema-aware processor, we can use our own datatypes for validation. We’ll cover the ways to create datatypes in the next section.

Note

We don’t cover the basic datatypes (xs:string, xs:integer, etc.) used by XML Schema here. See the discussion of [2.0] XPath 2.0 Datatypes” in Appendix B for all the details on those datatypes.
