Today I want to extend that support to include information from the social network about each user. In this case, the social network is Twitter. I could see situations where this namespace might be used to present information from status.net or Facebook, when they support lists, as Twitter has.
I'm going to use the name xSocial. The "x" could stand for one of two things: 1. XML or 2. Experimental, in the spirit of MIME types that are considered experimental or ad hoc, or proposals of future standards, and have an "x" in front of their names. In other words, I'm doing this because someone has to go first, and maybe someone already has, so this is my way of asking for comments (or, more likely, flames).
Here's a list of elements that may appear in documents that use the namespace.
xSocial:userId -- a string of characters that identifies a user.
xSocial:userName -- the user's name.
xSocial:userDescription -- a string of characters describing the user.
xSocial:userLocation -- a string, the location of the user.
