Std.Tactic.LabelAttr

"Label" attributes #

Allow creating attributes using register_label_attr, and retrieving the array of Names of declarations which have been tagged with such an attribute.

These differ slightly from the built-in "tag attributes" which can be initialized with the syntax:

initialize someName : TagAttribute ← registerTagAttribute `tagName "description"

in that a "tag attribute" can only be put on a declaration at the moment it is declared, and can not be modified by scoping commands.

The "label attributes" constructed here support adding (or locally removing) the attribute either at the moment of declaration, or later.
