Issue 27 - Proposal to vote - Setting link status in case of transitioncondition

[Assaf Arkin <arkin@intalio.com>]

Proposal to resolve issue 27 by adding the following paragraph to the
specification in the description of how links are handled (pages 64/65):

Note that the transition condition is evaluated after the activity has
completed. If an error occurs while evaluating the transition condition,
that error does not affect the completion status of the activity and is
handled by the activity's enclosing scope. In the case of
scopes, completion does not necessarily imply successful completion.  A
scope may suffer an internal fault and yet complete (unsuccessfully) if
there is a corresponding fault handler associated with the scope and
that fault handler completes without throwing a fault.
