 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 namespace (such as an ISO standard) or reverse domain name notation.
 
 Namespaces starting with `#` indicate that the label target should be associated with the label's value.
 This is a way of attaching standard nostr tags to events, pubkeys, relays, urls, etc.
