Re: [docbook-apps] Including character sets

In the XML 1.0 specification, section 2.8, it says:

"If both the external and internal subsets are used, the internal subset is
considered to occur before the external subset."

That means the PE has not yet been declared when you try to call it within
your internal subset.

Anyway, the DTD already includes all the character entities from ent/*.ent
in the DTD distribution.  You should not need to include them yourself.
