 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

 Namespaces starting with `#` indicate that the label target should be associated with the label's value.

 When using this NIP to bulk-label many targets at once, events may be deleted and a replacement
 may be published. We have opted not to use parameterizable/replaceable events for this due to the
 complexity in coming up with a standard `d` tag.

+Before creating a vocabulary, explore how your use case may have already been designed and
+imitate that design if possible. Reverse domain name notation is encouraged to avoid
+namespace clashes, but for the sake of interoperability all namespaces should be
+considered open for public use, and not proprietary. In other words, if there is a
+namespace that fits your use case, use it even if it points to someone else's domain name.
+
+Vocabularies MAY choose to include the namespace in the label, delimited by a `:` character.
+This may be preferred when defining more formal vocabularies that should not be confused with
+another namespace when querying without an `L` tag. For these vocabularies, all labels
+SHOULD include the namespace (rather than mixing qualified and unqualified labels).
