Assign a name to a branch of the version tree

[Jakob Reichl <ja...@gmail.com>]

What is the best way to assign names to branches of the version tree of a node ?
A node may have a main branch, one or several development branches and
 an integration branch.
One solution is to use labels, another one is to use a property. Are
there better alternatives ?

An application may be e.g. "give me the latest version on a certain branch".
