 Label Tag
 ----
 
-This NIP introduces a new tag `l` which denotes a label, and a new `L` tag which denotes a label namespace. A label MUST include a mark matching an `L` tag. `L` tags refer to a tag type within nostr, or a nomenclature external to nostr defined either formally or by convention. Any string can be a namespace, but publishers SHOULD ensure they are unambiguous by using a well-defined ISO standard or reverse domain name notation. Some examples:

+When using this NIP to bulk-label many targets at once, events may be deleted and a replacement
