It is my interpretation that the Poseidon output is not legal.

The namespace must be a valid URI [1], which means that it must be
preceeded by a scheme name followed by a colon, e.g. "http:" or "ftp:".
In the above case it looks like they are using URNs [2], in which case
the scheme is "urn:", so the correct namespace for UML should be

  xmlns:UML='urn:org.omg.xmi.namespace.UML'
