Technically no, the schema allows for the adding of 'anonymous' elements 
in certain parts of the document, for example in the metadata, data, and 
datum elements.  From the schema document:

Metadata =
       element nmwg:metadata {
               (
                       Identifier &
                       MetadataIdentifierRef? &
                       MetadataContent
               ),
               anyElement*
       }

'anyElement' in this case can be just that, any XML element.  In the 
Java classes we will add anything that resolves to an 'Element' into the 
childMap (From Metadata.java):

       else if(!(newChild.getLocalName().equals(""))) {           
           setChild((Element)newChild);
       }   

We originally allowed this to not be so rigid when it comes to accepting 
different messages that are not explicitly defined by a schema.

So the answer to that is 'yes', the handler is not really concerned with 
'misplaced' elements.  If we did add schema verification to the process 
we could probably catch something like this.  What did happen to the LS 
when you ran this test?  You said you expected an error code, but did 
the LS behave as 'normal'?
