I am having trouble trying to implement parameter entities so that i can repeat text multiple times within the DTD.

example XML code:


The address, street, city, postcode elements both have the same information. How would i reuse these sets of elements multiple times within a DTD document using parameter entity ? i know the key syntax is the % sign, but i can't seem to understand how to code it properly.

This is how it would look like, making some assumptions on cardinality and content model.

with the external dtd (specifically using parameter entity):

You cannot use parameter entities inside an internal subset, though.
