Hi PMC, hi all

As some of you already know, I am taking Andrea's place on the Feature Paging 
proposal.

We have been debating for a couple weeks now about it both on IRC and mailing 
list and would like to call for vote on it, at least someone has further 
concerns. Yet, I'll beg you for a quick process.

The proposal page is at 
<http://docs.codehaus.org/display/GEOTOOLS/Feature+paging+and+Query+capabilities>.

As per yesterdays geoserver IRC meeting [1] I've introduced to the proposal 
the use of org.opengis.filter.SortBy.NATURAL_ORDER as the minimum sorting 
support requirement for a FeatureSource to support paging, as opposed to the 
special property @gmlid, which may or may not be the feature type's "natural 
order".

Yet, asking to sort by feature id is still a sensible use case and should be 
handled as for any other property, regardless of the feature id being the 
native natural order or not.

Also changed QueryCapabilities.getSortNames():List<Name> by a query method:
supportsSorting(SortBy[]):boolean.

Regards,

Gabriel
