Requesting API for getting info about entity

Garry, please, make a XML version of each entity/prop/save/map information page that will show type (entity/weapon/prop/map/save) of a thing, its name, author, added, last-modified, downloads and likes like Valve did for Steam Community profiles and achievements pages (maybe by using xml=1 GET parameter)!

What for?

For web apps.
EDIT: What can?
