The next several panels show a set of UML
diagrams that represent the XML Schema Infoset model,
using the following notation:
- Each relationship or attribute Xyz, which we
will refer to as a feature Xyz in a diagram,
corresponds to a getXyz() method in Java for
accessing that feature.
- If the feature is many-valued (in other words, (0..*)), the
getXyz() method returns a
java.util.List interface, which can be modified directly using
standard java.util.List API.
- Otherwise, if the feature is single-valued, then a
corresponding setXyz() method is available for
A relationship with a black diamond corresponds to a
containment relationship. These form the basis for the
concrete tree structure of the XML Schema Infoset model.
A relationship with a white diamond corresponds to a
shared pseudo-containment relationship. It is used only for
documentation purposes since it is not logically
different from a relationship with no diamond. In general,
the white diamond relationships represent relationships
defined directly in the
XML Schema specification.
They are typically computed from other relations
and hence should not be modified directly.
The exception to this rule are relations involving
types. These consist of base-type, member-type,
item-type, and element- or attribute-type.
Note: The diagrams on the next several panels can also be
found in the org.eclipse.xsd/src/model/XSD.mdl model
