Suggested Wording for Issue 97

[ashok malhotra <ashok.malhotra@oracle.com>]

This issue has morphed into 2 related issues: clarification re. how 
qualified and unqualified intents are satisfied and
some explanation how intents, qualifiers and defaults may evolve:

CLARIFICATION Re. INTENT SATISFACTION

Add after the first (and only) para in 4.12 the following

If the unqualified form of a qualifiable intent is attached to an 
element, it can be satisfied by a policySet that
specifies any one of qualified forms of the intent in the value of its 
@provides attribute.
Or it can be satisfied by a policySet which @provides the unqualified 
form of the intent. If the qualified form of the intent is attached to 
an element then it can be satisfied only by a policy that @provides that 
qualified form of the intent.

WORDING Re. EVOLUTION OF INTENTS

Add a new para after the last para in section 3.1

The normatively defined intents in the SCA specification may evolve over 
time.
New intents may be added, additional qualifiers may be added to existing 
intents and the default
qualifier for existing intents may change.  Such changes would cause the 
namespace for the
SCA specification to change.
