Supposing (a _big_ supposition, see below), your schema is described
by a single schema document, then why doesn't the following sketch
work:
xsd:complexContent/*[self::xsd:restriction or
self::xsd:extension]/xsd:complexType |
/xsd:schema/xsd:complexType[@name=current-node()/xsd:complexContent/*[self::xsd:restriction or
self::xsd:extension]/@base] |
xsd:simpleContent/*[self::xsd:restriction or
self::xsd:extension]/xsd:simpleType |
/xsd:schema/*[@name=current-node()/xsd:simpleContent/*[self::xsd:restriction or
self::xsd:extension]/@base and
(self::xsd:complexType or self::xsd:simpleType)]
It has to be said that navigating schema _documents_ when what you
really want is to navigate schema _components_ is a pain. The XML
Schema WG is working on a story about Schema Component Designators, to
address this problem.
