Difficulty seeing error

If I try to validate this xml...
<?xml version="1.0" encoding="utf-8" ?>

....the validation complains that...
Element 'http://www.somewhere.fun.com/Funcalc:FuncalcParameters' has invalid
child element 'TransId'. Expected
'http://www.somewhere.fun.com/Funcalc:TransId
http://www.somewhere.fun.com/Funcalc:CalcType'...
Why does it mention "CalcType"? Altering the schema so that "CalcType" is
further down results in the validation complaining about
'http://www.somewhere.fun.com/Funcalc:TransId
http://www.somewhere.fun.com/Funcalc:SR'. Can anyone see what's going on?
Thanks

I think I found my error. By simply adding the namespace "a:" to all of the
instance doc's elements, everything behaves as I would expect. It was not
just a "TransId" or "CalcType" problem - in fact all of the elements needed
to be qualified in the "a:" namespace. But still I wonder why if all of the
elements needed "a:", why did the error message only complain about the
first two? Oh well...

Hi Marty,

While I can't answer your question myself, I have sent it on to the team
that supports XML in developer Support. I'll get an answer to you ASAP.

Here is what I see.

1> Xsd seems simple enough. You have an element called "FuncalcParameters"
which has 10 child nodes (some of which may be present and others are
required).
2> Required items are CalcType, SR, ARM and SRMP.
3> All can only occur once in sequence.

From the Xml, I see the following.

1> We are associating the prefix "a" with
"http://www.somewhere.fun.com/Funcalc"
2> FuncalcParameters is associated to the prefix (and therefore namespace)
"a"
3> Funcalc does not have ANY children to validate against and should fail
on the "CalcType".
4> Because the first child HAS to be TransID, it should also fail because
there is no a:TransID. (remember that TransID and a:TransID are totally
different.)
TransID internally is TransID
a:TransID internally is
TransID:http://www.somewhere.fun.com/Funcalc
So, there are a few ways to workaround this.

1> Remove the "a" from the xmlns:a="http://www.somewhere.fun.com/Funcalc".
If you choose to leave the prefix "a", then you will have to prefix ALL
elements belonging to that namespace with "a". Also, remember, when you
place a sequence into the element, you are basically saying that the
elements will be in that order and any other order is incorrect.
2> Prefix all elements with "a" and associate it with the namespace.

It would always be best to do #2, however, many use #1 for ease.

Let us know if you need additional clarification.

Thanks
