[NEW ISSUE] Can Implementation change property values afterinstantiaion

[Tom Rutt <tom@coastin.com>]

Title:  Can an Implementation change property values after instantiation

Nature of problem:

The assembly spec does not state whether property values, once injected 
into an
implementation instance at component instantiation within a composite, 
must keep
the same value througout the active lifetime of that instantiation.

Some users might be tempted to treat SCA properties as component state 
variables,
which would require the implementation to change their values at the 
state of the component
progresses during its lifetime.

Proposes Solution:

The TC should decide whether or not property values are expected by SCA to
remain static throughout the lifetime of a component instantiation.

If the TC decides that property values are always static, text should be 
added to make
that clear.

If the TC decides that property values may be dynamic, then it might be 
best to
add an attribute the property definition to denote whether its value is 
static or dynamic.
