For a lot of purposes the limit is fine even with xml or json - it
gives back the (up to) 10 mostly likely matches.  Perhaps if you could
give a use case to explain why you would like this limit removed I
could suggest other options.

The limit of 10 items is not a display choice but a performance
choice. It is there to prevent a single query for using too much
resources and blocking usage by other people and to the ensure that
the response is returned in a reasonable time.

Have you investigated the possibility of using the more_url ? This
already allows you to obtain the next batch of 10.
