+\label{authorize}
+
+This specification is currently a draft and requires that each requirement be
+verified and authorized for development.
+
+An authorization indicates that a member of the indicated party or parties with
+sufficient knowledge on topic affirms that the requirement is---to the best of
+his or her knowledge---accurate and suitable for incorporation into an
+implementation of the specification.
+
+\p{signcomp} A signature line next to content that is not a numbered paragraph
+is a \dfn{significant component}.
+
+\begin{ex}
+  \signline
+  This example is not a paragraph but still contains a signature line; it is
+  therefore a significant component under the definition of \pref{signcomp}.
+\end{ex}
+
+Each paragraph and significant component of the specification, unless incomplete
+or previously authorized, contains a line that may be used for the initials of a
+member of the party indicated in parenthesis. If multiple parties are
+applicable, they will be separated with slashes.
+
+Only a member of the party knowledgeable on the topic \shall provide their
+authorization.
+
+An authorization is performed by (a)~signing one's initials on the provided line
+or (b)~indicating the paragraph number (or, for significant components, an
+appropriate notation containing at least the section number and a unique
+identifier for the significant component itself) via some \unspecified\ method
+of correspondence that explicitly indicates each and every individual
+authorization.
+
+A particular authorization is valid until the authorized paragraph or significant
+component is modified from its authorized form.
+
+Signature lines with no authorization party listed \shallnot be authorized until
+at least one party has been chosen.
