Glancing at the Filter Encoding specs (1.0.0 and 1.1.0) it looks like 
there are some typos in the 1.0.0 docs.  The prose mentions escapeChar 
but the examples use escape.  When I've pointed out discrepancies like 
this before, I've been told the schema is the final word.

http://schemas.opengis.net/filter/1.0.0/filter.xsd
http://schemas.opengis.net/filter/1.1.0/filter.xsd

So it is "escape" in 1.0.0 and "escapeChar" in 1.1.0.  This should be 
patched in the filter formats.
