Kauneya,
XSD models elements (and everything else) according to the XML Schema
specification's component model. So an element has these properties:
http://www.w3.org/TR/xmlschema-1/#Element_Declaration_detail s
And information about "cardinality" is modeled as a particle:
http://www.w3.org/TR/xmlschema-1/#Particle_details
The spec carefully outlines how an element information item maps to the
component model (i.e., how it maps to both an element declaration component
and a particle component):
http://www.w3.org/TR/xmlschema-1/#declare-element
It might help to look at examples:
http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/xsd- home/docs/javadoc/org/eclipse/xsd/util/XSDPrototypicalSchema .html
