Hi Roger,
Seems OK.
You missed a closing "]" on Slide 5 :)
Oh, and BTW, do you think this is streamable:
text()[1]
Maybe the Spec. says "yes", but I don't believe so.
Cheers,
Dimitre

Hi Folks,
Suppose you want to count the <head> elements within the <section> elements.
You might use this simple XPath expression:
count(//section/head)
However, that has a subtle problem when used in a streaming program.
I created a few slides that describe the problem, as well as the solution:
