LAST CALL COMMENT 1/31/2005: Variable Clarification in Section 2.4

Section 2.4.2 indicates:
A Variable defined using the attribute channelType specifies Channel 
Capturing Variables. The attributes informationType and channelType are 
mutually exclusive.

Assuming this is true, a slight revision is recommended to clarify this 
text in Section 2.4:

FROM: Both Variables and Tokens have Information Types that define the 
type of information the Variable contains or the Token references.
TO: Information Exchange and State Capturing Variables and Tokens have 
Information Types that define the type of information the Variable 
contains or the Token references.
