Code review comment for lp:~zorba-coders/zorba/feature-json_parser

I think William is right. We should have a couple of examples which help the user to get started with this module. Those could either be inline in the text or links generated using the @example xqdoc tag.

The serialize functions should be annotated %ann:streamable because they return a streamable string (see modules/com/zorba-xquery/www/modules/fetch.xq).

Some error codes lack a prefix (e.g. ZJPE0001). If I understood correctly, it should be zerr:ZJPE0001. Otherwise, the user doesn't know how to catch the error.

Under which circumstances does json:parse return the empty sequence? What does json:serialize return if the input is the empty sequence?
