First letbs do XSLT 2.0. Your requirement translates directly into syntax:

count(
  preceding::instrText
  [starts-with(., bHYPERLINKb)]
  [ancestor::sect is current()/ancestor::sect]
)

The only problem is the bisb operator which requires 2.0. In XSLT 1.0 you
can substitute generate-id():

count(
  preceding::instrText
  [starts-with(., bHYPERLINKb)]
  [generate-id(ancestor::sect) = generate-id(current()/ancestor::sect)]
)

I donbt see how you get 4. Which 4? From your description, I would expect to
select those labelled 3, 4, and 5.
