Bruno, your patch looks really good. patch-2132-r9689-A1.diff brings minor modifications here and there:

CSWGetDomain/v2_0_2.js

• add copyright
• add PropertyName and ParameterName to prototype
• make read and write API methods
• replace new Array() by [] (OL convention)

CSWGetRecords/v2_0_2.js

• same kinds of changes as for CSWGetDomain
• change from "if (ResponseHandler && ResponseHandle instanceof Array)" to "if (ResponseHandler instanceof Array)"

Tests pass in FF3. I think this is good to go. I'll wait a couple of days before commit, in case other developers want to have a look..

Thanks for the review Eric. patch-2132-r9695-A2.diff simply revert defaultPrefix to "csw" in CSWGetDomain format.
