In XSD 1.1, vendors are allowed to add their own types and facets. This mechanism allows you to include conditional code depending on the presence of these implementor-defined types and facets. As with function-available() in XSLT, it also allows finer-grained control if you expect to be running on processors (like Saxon 9.2) that implement some new features of XSD 1.1 but not all.
