Fix passing x-context for explain in formURL, add passing scanClause to fromURL. Add comments to explain2json. Change explain2view so it provides full information on page request and only the most relevant for ajax requests. Commented and fixed scan2json. Fixed generating the scanClause in scan2view for search links, fixed using displayTerm if it exists in XSL 1.0. Added a 3rd party module that can generate JsonML and various other XML -> JSON representations (XSL 2.0 only)
