Summary: Reserved prefixes and namespace names
Initial Comment:
Expat does not reject illegal declarations for reserved
prefixes and namespace names. From the errata
for the Namespaces in XML 1.0 specs:
<quote>
The prefix xml is by definition bound to the namespace
name http://www.w3.org/XML/1998/namespace. It may,
but need not, be declared, and must not be bound to
any other namespace name. No other prefix may be
bound to this namespace name.
The prefix xmlns is used only to declare namespace
bindings and is by definition bound to the namespace
name http://www.w3.org/2000/xmlns/. It must not be
declared. No other prefix may be bound to this
namespace name.
</quote>
The following four not-well-formed documents are not
rejected by Expat:
<?xml version="1.0"?>
<!-- Reserved prefixes and namespaces: declaring the
xml prefix incorrectly -->
<foo xmlns:xml="http://example.org/namespace"/>
<?xml version="1.0"?>
<!-- Reserved prefixes and namespaces: binding another
prefix to the xml namespace -->
<foo
xmlns:yml="http://www.w3.org/XML/1998/namespace"/>
<?xml version="1.0"?>
<!-- Reserved prefixes and namespaces: declaring the
xmlns prefix with its correct URI (illegal) -->
<foo xmlns:xmlns="http://www.w3.org/2000/xmlns/"/>
<?xml version="1.0"?>
<!-- Reserved prefixes and namespaces: declaring the
xmlns prefix with an incorrect URI -->
<foo xmlns:xmlns="http://example.org/namespace"/>

Finally fixed in expat.h rev. 1.75 and xmlparse.c rev. 1.142.
Fix contributed by Peter van der Beken.
Thank you, Peter.
We should be very close to passing all test cases in the
XML-Test-Suite.
Left open for regression test case.
Assigned to Fred.

Lowered priority to 3.
This bug really doesn't have much impact in practical
applications, but fixing it may add noticeable overhead.
