To address some of these comments we would need to do some work on the test suite.

My answers inline.


(I can't run the HTML test generator)

The recorded results are right - it looks like the HTML generator does not 
respect the "index=" in the results files.

It would be clearer to SRX files for ordered results - the HTML generator 
doesn't seem to understand, looking at their use elsewhere.

It's legal.  Any keyword can be used as a prefix.  This happens in the 
tokenizing part of the grammar because "FILTER:" is a longer match than "FILTER"

Old syntax.  We should clear all these up.

Open world issue.  != means not known to be different so unless the processor 
knows about the types, they are not known to be different values so != does 
not return true.
