[security-services] ISSUE: core-27: RespondWith specified queriesreturn AN assertion

[Jeff Hodges <Jeff.Hodges@sun.com>]

Section 3.2.1.1 of core-27 effectively
specifies that a Responder can return only one assertion in response to a given
request, because all the values of RespondWith specify return of "an
assertion", and the specified default behavior if RespondWith is absent from
the request is the behavior associated with a RespondWith value of
#SingleStatement. 

This is in conflict with section 3.4.2 line 1192-1193 which states..

  The <Response> element specifies the status of the corresponding SAML 
  request and a list of zero or more assertions that answer the request.


The "an assertion" language in Section 3.2.1.1 of core-27 needs to be cleaned
up to bring it in line with section 3.4.2.
