Declaring character entities

[Ben Ryan <b_ryan@c-elect.co.uk>]

Hi,
	Having just completed a schema and starting to write to samples for I
came across the problem of an undeclared entity. Where exactly do you
declare entities in schemas?. I will be using a large amount of
characters and symbols and would like to reuse the definitions I have
some how and not have to resort to using numeric character references.

Thanks,
	Ben
