[Rich Thompson <richt2@us.ibm.com>]

Document: Spec
Section: 6.1.4
Page/Line: 31/19
Requested by: Michael Freedman
Old text: Note that any key caching systems use locate this markup ...
Proposed text: Note that any key used by the caching system to locate this 
markup MUST include the MarkupParams structure that was current when the 
content was originally cached.
Reasoning: I like it better ;-) 
[Eric VanLydegraf] I have suggested a fix for this one as well change 
request #16, but I like yours better so would promote this one over mine.
