Description Gilbert Pilz 2009-11-14 04:06:29 UTC 
The description of Pull contains the following paragraph:

"Upon receipt of a Pull request message, the data source MAY wait as long as it deems necessary (but not longer than the value of the wsen:MaxTime element, if present) to produce a message for delivery to the consumer. The data source MUST recognize the wsen:MaxTime element and return a wsen:TimedOut fault if no elements are available prior to the request message's deadline. Note, however, that this fault SHOULD NOT cause the enumeration context to become invalid (of course, the data source MAY invalidate the enumeration context for other reasons). That is, the requestor can issue additional Pull requests using this enumeration context after receiving this fault."

It's not clear why the data source would wait, etc.

General Proposal: reword for clarity
Comment 1 David Snelling 2010-01-28 19:12:17 UTC 
Proposal:

The data source MUST recognize the wsen:MaxTime element and return a wsen:TimedOut fault if no
elements are available prior to the request message's deadline. 

However, that this fault MUST NOT cause the enumeration context to become invalid and the requestor can issue additional Pull requests using this enumeration context after receiving this fault.
Comment 2 Doug Davis 2010-02-15 14:02:26 UTC 
Minor word tweaking to Dave's proposal:

Proposal:

The data source MUST recognize the wsen:MaxTime element and return a
wsen:TimedOut fault if no elements are available prior to the request 
message's deadline. 

However, this fault MUST NOT cause the enumeration context to become
invalid and the requestor can issue additional Pull requests using this
enumeration context after receiving this fault.

resolved with comment 3 using the word "consumer"
