Re: State variable test

/ Alex Milowski <alex@milowski.org> was heard to say:
| Shouldn't $p:position and $loop_index be the same?  We say:
|
| "In contexts where a sequence of documents is being processed, for example,
| in the test expression of a p:matching-documents, this variable returns the
| position of the current document within the sequence. Numbering begins at
| one."
|
| The for-each processes a sequence.

Yes. Having thought about this some more, I think p:document-position()
inside a for-each ought to be the same as the index.

If we said that the p:document-position() inside a viewport was also the
same as the index, then I think we could do away with the index
altogether.

Inside a loop, it would always be the same as p:document-position(). If
a user wanted to be able to refer to the counter in some outer loop,
he or she could set an option and refer to that.

So now we only need:

  p:episode()

and

  p:document-position()

I like that better.
