Those are used for resolving the text content of 
the references made in your XML document.

A schema is used for defining the model of your document.

The two purposes are different.

I don't know what you mean by that ... entities 
and elements are different things.

What is it you are trying to do with that reference?

Solution to what?

>Thanks for helping me,

Help us answer you ... at least I for one don't know what you are asking.

An document isn't an XML instance if there are no 
declarations for entities that are being used, 
because then the document isn't well-formed.

W3C Schema validates well-formed documents.

W3C Schema was defined long after XML was 
defined, so it isn't possible to somehow express 
entity declarations in W3C Schema in a way that a 
well-formedness check of the document will find the document to be XML.

I hope this helps.
