Yes, that seems like option #1.

But we need to hear (why) from the people who felt that expanding in all cases
was onerous.  Seems like doing a search and replace to proliferate the
expansion would not be that bad.

Certainly, the guideline here expects intelligence from the UA that the format
specifications generally do not provide.  The format-defined semantic model of
HTML and XML does not particularly support the recognition of "another use of
the same [element content] as was given an expansion above."

A counter-example to that general statement is the define/use cycle in SVG  
Here you can embed the expansion in the definition and use the symbol
repeatedly with terse 'use' references.

A dictionary would be a third-party way to supply the expansions.  This is
likely to refer to the terms it defines not by location or node ID but by
spelling.  This is why we need XML Schema and _pattern matching which is not
predicated on reference by URI_ in order to build the infrastructure we need. 
But regular expressions and pattern matching are predicated on the character
model at least, if not the infoset.

This question has coordination written all over it.

The issue about how burdensome it is to expand all instances means GL has a

The issue about can the UA process the expansions (if only given once)
a UA/PF dependency, so both those groups have a stake, here.

ER is the lead group as far as experimenting with the application of patterns
and rules.  So we don't want to fail to check with them.
