Peter, There is no direct way to find the id of a schema type, but there is a work around: each compiled schema type points to its xsd file (see SchemaComponent.getSourceName()), once you have the file it's possible using xpath to find the type definition and the value of it's id attribute. If I'm not mistaken we're probably the very few people if not the first to ask about id attribute related to a schema type.
