Re: [wsdm] Thoughts on "transaction" wording for MUWS

[John DeCarlo <jdecarlo@mitre.org>]

Here are some suggestions:

[TRANS.001] The Manageability Interface MUST support, as part of the 
management information, a "unit of work" that consists of multiple 
actions against a single resource.

[TRANS.002] The Manageability Interface MUST support, as part of the 
management information, a "unit of work" that consists of the same 
action applied to multiple resources that the manageable resource knows 
about.

What do you think?
