Can biztalk accept input xml with extra tags in it? if yes, How?

Question

I have the following sample input xml:
<Students Class='xyz'>
<Student count='0'>
<FName value='Alex'/>
<LName value='James'>
<Age value='22'>
<DOB value='01/01/2001'>
<ID value='123'>
</Student>
<Student count='1'>
<FName value='Victor'/>
<LName value='Brown'>
<Age value='23'>
<DOB value='02/12/2000'>
<ID value='541'>
</Student>
</Students>
And my input schema accepts the xml which is similar to the above xml except it does not have <Age> and <DOB> tags in it. which means that the <Age> and <DOB> tags are extra tags in my input xml which is not
required by the input schema.
Question: is it possible in biztalk to accept the above xml as it is (i.e. along with <Age> and <DOB> tags) to populate the schema which accepts all xml except <Age> and <DOB> tags?
Can it just pick up the required tags and populate the input schema?
Thanks

Automatic change in the published schema on the basis of a received messages is still science fiction :)
There is still a way for you to handle these messages. If in the receive pipeline you do not enforce schema validation, in your orchestration you use bound receive ports [not direct ports] and receive the message as an XMLDocument, you should still be able
to receive/process the document.
The ability of an predefined Schema to accept additional data elements is called an OPEN CONTENT Model [refer
http://msdn.microsoft.com/en-us/library/aa468557.aspx] and you can create a schema to support such things if that is how you expect messages. So in your schema you define elements of type
"xsd:any" to accept content changes even with schema validation turned on.
