Summary: Bug with attr defaults and external PE's

Initial Comment:
Take a look at this document:

<!DOCTYPE doc [
 <!ATTLIST doc a CDATA "D4A">
 <!ENTITY % x SYSTEM "x.ent">
 %x;
 <!ATTLIST doc b CDATA "D4B">
 ]>
<doc>Hello.</doc>


If you process this with expat 1.95.3 and without
processing the external entity %x; expat reports the
element doc with two attributes: a="D4A" b="D4B".

You could easily check this with the xmlwf tool, using
the -d option.

This is wrong. See the last paragraph of the XML rec
Second Editoin 5.1: "[...][T]hey must not process
entity declarations or attribute-list declarations
encountered after a reference to a parameter entity
that is not read, since the entity may have contained
overriding declarations."

As far as I see, this bug was already in 1.95.1, then
fixed in 1.95.2 and showed up again in 1.95.3

Small correction:
The file Rolf3_2.ent is actually not needed, since it
won't be read by Expat, but I attached it anyway.

Patch # 578161 includes a fix for this bug.
Please test.

I have also attached a test document (files Rolf3.xml,
Rolf3_1.ent and Rolf3_2.ent) which test section 5.1 for
entity declarations. There is an entity reference %z; in
Rolf3_1.ent which needs to be skipped, since there is
no declaration for it, and this is not a WF error.
More details in the comment within Rolf3.xml.

Yes, this is a bug, and was probably introduced by me.
Now I finally beging to understand why the dtd.complete flag
was used in such strange ways... :-(

So, I guess this one is for me,
