Hi,

I have trouble understanding how 'anySimpleType' is handled if comparing 
values. Xerces and XSV seem to differ here.

Identity-constraint example:
(using Xerces-J 2.5.1, XSV 2.5-2, MSXML 4.0)

<sequence>
   <element name="b" type="anySimpleType"/>
   <element name="c" type="float"/>
</sequence>

<b>1.0</b>
<c>1.0</c>

with the value of 'c' being a keyref to the key value of 'b'.

Results: XSV and MSXML do not find the referenced key, Xerces does.

if both types are 'float':

Results: All tree validators find the referenced key.

I cannot find a hint for 'anySimpleType' being not comparable with the
primitive types. The PER for datatypes says:

"anySimpleType is considered to have an unconstrained lexical space and 
a =B7value space=B7 consisting of the union of the =B7value space=B7s of all=
 the 
=B7primitive=B7 datatypes and the set of all lists of all members of the 
=B7value space=B7s of all the =B7primitive=B7 datatypes."

Further "4.2.1 equal" says:

"if a datatype T' is =B7derived=B7 by =B7restriction=B7 from an atomic datat=
ype 
T then the =B7value space=B7 of T' is a subset of the =B7value space=B7 of T=
. 
Values in the =B7value space=B7s of T and T' can be compared according to 
the above rules "

Can someone explain?

Greetings,

Kasimier
