That's my understanding too leaving only such things as well-known
entities like &amp; etc. 

I guess one could entertain the idea of defining a serialization that
introduces a DTD which is not reflected in the SOAP message infoset.
Similarly one could imagine defining other information items such as
additional attributes or elements that are also not reflected in the
SOAP message infoset.

It is not clear to me, however, that a straight forward reading of the
Infoset spec would enable such additional information items to be
present as it would require some form of agreed infoset transformation
to be performed by the communicating parties. The definition of the
"application/soap+xml" media type certainly doesn't elude to such a
transform.
