RE: [uddi-spec] Use of maxRows and listHead in V3

["Rogers, Tony" <Tony.Rogers@ca.com>]

If we return no results on maxrows = 0, but return the number of results, then the program can use that number to prepare for a second call to receive the results - that's the usual rationale for including a "return 0 results but tell me how many there are" call. It's less useful for these results, because they vary in size, but that is what I'd see it being used for. That, or some statistical analysis application, where they are interested in the number of results rather than the content.

 

Anyway, it seemed to me that there was some (albeit small) use for accepting maxRows=0.

 

As for negative numbers - you have a point - maybe we should reject the request. Would you care to suggest a suitable error?
