Comment 1 Pierre Delisle 2004-01-20 20:17:28 UTC 
Reinstated the extra/spath directory which contains
some very fine code from Shawn. This code is used
by the XML Filter example.

SPath is an example of a parse filter (XMLFilter) for DOMs.  
Its goal is to support the XML Filter example and to help developers
understand what we intended by our 'filter' support.

[Had been removed by error because I thought this was a vestige
of our early attempts at experimenting with various
expression languages]
