Content Models

XSD supports a few content models:

  1. empty: no child elements or child character data allowed

  2. simple: No child elements are allowed; the character data must conform to a given simple type

  3. non-mixed, group: The group describes the elements that are allowed; no character data may occur outside the child elements.

  4. mixed, group: The group describes the elements that are allowed; character data may be mixed in, occurring outside of child elements.
