Validating Soap Envelope

[Patrick Brunmayr]

Hello

I have a big Problem with validating a Soap Envelope. I have
downloaded the xsd for a soap envelope from http://schemas.xmlsoap.org/soap/envelope/

The validation succeeds as lonng as i don't use elements in body with
a xsi:type attribute!

The Problem is that fooerson is an abstract type and foo:driver is
dervived from it. So using a fooerson is not allowed until specifing
the type of person per xsi:type. The below example demonstrates this
problem. When i try to validate this with the saxonica validator
following error occurs

Validation error on line 6 column 60 of test xml:
Unknown type {foo:driver} specified in xsi:type attribute SAXON
8.9.0.3 from Saxonica validate complete

The definition of of sopa body says

<xs:sequence>
<xs:any namespace="##any" minOccurs="0" maxOccurs="unbounded"
processContents="lax"/>
</xs:sequence>

So when elements from other namespacas are found, try to find a schema
defintion otherwise don't care

In my example there is no schema defintion for "foo:driver" because
the soap schema can not know about the schema where "foo:driver" is
defined! I have no possibility at this stage of validation to include
the schema defintion for those types. I need the xsi:type attribute
coz the sopa body elements will be validatet at later stage. Dont
specfifing the xsi:type attribute whill pass the soap envelope
validation but not thr later body elements validation! How can i solve
this

My Sample Soap Request

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xs="http://
www.w3.org/1999/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-
instance"
xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/
envelope11.xsd">
<env:Header/>
<env:Body>
<fooerson xmlns:foo="http://foo" xsi:type="foo:driver">
</fooerson>
</env:Body>
</env:Envelope>

The validation succeeds as long as i don't use elements in body with
a xsi:type attribute!

If you specify xsi:type, you need to provide information so the system
can find the schema which defines that type, as well as the schema for
the soap envelope.

The "any" means that the soap wrapper doesn't care what its contents are
-- but that does NOT mean they aren't checked for consistency on their own.

In my example there is no schema defintion for "foo:driver" because
the soap schema can not know about the schema where "foo:driver" is
defined!

Most systems for providing the schema information -- and specifically
the schemalocation hint attribute -- can specify multiple schema
documents that will be combined into a single effective schema. That's
what you need to fix, I believe.

There really ought to be articles and examples of this on the web by
now. I'm not currently hacking around with Soap so I don't have a
pointer handy, but may I suggest that Google Is Your Friend?
