Aggregate sitemap node.

View handling in aggregation

• map:aggregate can have a label, but doesn't match view from-position="first" like generators
• each map:part can have a label
• if at least one of the parts has a label matching the current view, only parts matching this view are added. Otherwise, all parts are added.

For more info on aggregation and views, see the mail archive here or here.
