[Speaking on behalf of reviewers from IBM, not just personally.]

Section 2.1.2

The definition of the "Current date and time" component states, "If 
invoked multiple times during the execution of a query or transformation, 
[fn:current-date, fn:current-time, and fn:current-dateTime ] always return 
the same result."

XPath should only impose this requirement for a single expression.  It is 
up to the host language to impose this sort of requirement across multiple 
expressions (like a transformation in XSLT).

In addition, section C.2 indicates that the scope of "Current date and 
time" is "global", which "indicates that the value of the component 
remains constant throughout the XPath expression."  That contradicts the 
statement quoted in 2.1.2.  2.1.2 should be changed to be consistent with
