Well, then, your hopes won't be dashed!
You might consider conditionalizing these little beasties,
using the Online and Print build tags that RH provides. Prepare an
expanded version for them that will only appear in Print docs, and
set the conditions for each separate content. Then, your
Conditional Build Expression (first window of Generate wizard) for
the PDF is "NOT Online" and for the WebHelp is "NOT Print."
Good luck,
Leon
