Hi Purvesh,

your content model is deterministic. The best way to visualize it is by
drawing a state diagram (see attachement). There is always only one way
to go.

Note that there is a fancy way to note your content model in SGML, that
reappears in XML Schema definitions as the 'all' tag. In SGML it is:

<!ELEMENT a ( x & y )? >

Greetings,

	Patrick
