      Hi George,

I'm sorry for not getting back to you earlier.  I was sick all last week.
Here are some results that was found while I was away:

1. The GML 3.1.1 is still being developed and that is why you couldn't find
it.

2. one of the team members found out that the error was caused by the
grids.xsd which is part of the GML 3.1.1 suite.

3. The fix is as follows:

Change:

############
<element name="RectifiedGrid" type="gml:RectifiedGridType"
substitutionGroup="gml:Grid"/>
############

To:

############
<element name="RectifiedGrid" type="gml:RectifiedGridType"
substitutionGroup="gml:_ImplicitGeometry">
               <annotation>
                       <documentation>Should be substitutionGroup="gml:Grid"
but changed in order to accomplish Xerces-J schema validation</documentation>
               </annotation>
############

This has fixed the ambiguity error.

I want to thank you for answering my email.  I'm sure that you would have
been able to track down the problem as you have done so in the past when I
post to this list but it seems like someone else looking at GML 3.1.1 beat
you to it.

Thanks again.

John

Hi John,
I cannot find GML 3.1.1. Can you point us to that ?
The error directs to the GridDomainType and DomainSetType. The first 
seems not to be a valid restriction of the second. The 
rcase-Recurse.2 
points you to the following part of the spec that is related 
with the error:
***
2 There is a complete ·order-preserving· functional mapping from the 
particles in the {particles} of R to the particles in the 
{particles} of 
B such that all of the following must be true:
2.1 Each particle in the {particles} of R is a ·valid restriction· of 
the particle in the {particles} of B it maps to as defined by 
Particle 
Valid (Restriction) (§3.9.6).
2.2 All particles in the {particles} of B which are not 
mapped to by any 
particle in the {particles} of R are ·emptiable· as defined 
by Particle 
Emptiable (§3.9.6).
***
The best thing is allow us to reproduce the error. Otherwise 
send us at 
least the DomainSetType definition.
Best Regards,
George

Hi,
We have been trying to validate the GML version 3.1.1.  We 
have managed to
track down 140 of the 144 errors in the XML Schema.  The 
last four errors are
really puzzling.  Could someone please help with 
interpreting and fixing the
errors?
The errors are:

  </complexType>
Can anyone see the problem?
