ebBP 3/7/2005: Comment re: Condition 'Variables' (wd 10)

["Monica J. Martin" <Monica.Martin@Sun.COM>]

In Tuesday's call we discussed that use of variables could be useful for 
pre- and post-conditions, beginsWhen and endsWhen.

========================
Add to this paragraph in Section 4.6.7.1 that says:
Business Transaction Activities, Complex Business Transaction Activities 
and Collaboration Activities MAY define business rules with the 
beginsWhen, endsWhen, preCondition and postCondition elements. These 
elements MAY be used for annotation purposes.  If the expression 
attribute is rendered as computable, the BSI MAY use these attributes at 
run-time.

[add] If desired, variables MAY be used to further enable pre- and 
post-conditions, beginsWhen and endsWhen attributes, as they are
of type ConditionExpressionType. For example, an XSLT variable could be 
used for these attributes and allow values to placed in them.
Variables are semantic enablers discussed in Section 4.6.8. [add]
