KDM12 — Clarify the intent of KDM ontology (rh-7)

Related to section 7, paragraph 13, bullet 3

"KDM defines an ontology for describing existing software systems"

Clarify whether the intent is an ontology for systems or software assets of system. These are very different subject matters

Add to page 10 (ontology bullet), and move that bullet to the end of the list:
The ontology defined by KDM is related to the elements of existing software systems, and the
relationships between these elements, as well as the elements of the operational environment of
the software system. KDM ontology addresses both physical elements (for example, a procedure,
a variable, a table), which are originally represented by language-specific artifacts of the software
(for example source code), as well as logical elements (for example, user interface elements,
concepts that are implemented by the software, architectural components of the software, such
as layers, etc.)
