That sounds like a bug - you should step through the code and see what
happens when it finds a boolean. This document writer thing is focused
on the older specifications etc... we have a current schema driven
xml encoding technology that is easier to maintain. Please check out
http://docs.codehaus.org/display/GEOTDOC/05+GTXML+Parsing+and+Encoding
and see if it handles boolean correctly for you?
When you do have a patch please create a jira bug report and attach
the patch w/ test case.
As for DocumentWriter please reivew FilterComplexTypes line 1408 ...
the encode method here looks to be responsible for encoding Literal
expressions.
