1346696 - Store attr content values as two strings

Status: NEW

Description

[Manish Goregaokar [:manishearth]]

We currently store them as a string, of the format `<namespace map id>|<value>` (or just `<value>` if there is no namespace).

We should store it as two things, and serialize it correctly (converting the id back to a namespace prefix).

(We could also keep storing the namespace as the namespace ID number.  The key thing would be to separate it from the local name, so that we don't have ambiguities in the packed-together string.)
