The new element <Schema>, a child
of the <XmlApplication> element, specifies
the path of a Schema file in the structapps.fm Structured
Application file. If instance documents use namespaces, the property <Namespace> in <XmlApplication> must
be set to true.
In order for a Structured Application to be selectable in the Use
Structured Application list while importing a document
that is associated with a schema, the schema’s root element must
be included in the application’s <DOCTYPE> in
the <XmlApplication> element.
