This is probably off-topic for xsl-list - for XML Schema specific
questions use the xmlschema-dev mailing list.

To check for uniqueness, use xs:unique :) If you added the following
to the definition for <file> it would do what you need:

<xs:unique name="id">
  <xs:selector xpath="entry"/>
  <xs:field xpath="@id"/>

Alternatively just type the id attribute as xs:ID, as long as your ids
are all valid ids.
