CORBA3 — Corrections in XML DTDs for packaging

In the Adopted CORBA Components Specification (formal/02-06-65),
page 6-4, section 6.3.2.1, the version attribute of the softpkg
element is tagged as #OPTIONAL and is tagged as #IMPLIED at page 7-5.
As #OPTIONAL is not valid in XML, then replace it by #IMPLIED.

In chapter 7, the softpkg XML DTD does not contain the
ins and objref elements which they are used by the repository
element described at page 7-4. Add them.

Proposed revised text:

In formal/02-06-65:

At page 6-4, section 6.3.2.1, replace #OPTIONAL
by #IMPLIED for the version attribute of the softpkg element.

At page 7-3, add before the humanlanguage element

<!ELEMENT ins EMPTY >
<!ATTLIST ins
name CDATA #REQUIRED >

At page 7-4, add before the os element

<!ELEMENT objref EMPTY >
<!ATTLIST objref
string CDATA #REQUIRED >
