+<t>
+  There are certain aspects of the HTTP Authentication Framework that put
+  constraints on how new authentication schemes can work:
+</t>
+<t>
+  <list style="symbols">
+    <t>
+      Authentication schemes need to be compatible with the inherent
+      constraints of HTTP; for instance, that messages need to keep their
+      semantics when inspected in isolation, thus an authentication scheme
+      can not bind information to the TCP session over which the message
+      was received (see &msg-orient-and-buffering;). 
+    </t>
+    <t>
+      The authentication parameter "realm" is reserved for defining Protection
+      Spaces as defined in <xref target="protection.space"/>. New schemes
+      &MUST-NOT; use it in a way incompatible with that definition.
+    </t>
+    <t>
+      Authentication schemes need to document whther they are usable in
+      origin-server authentication (i.e., using WWW-Authenticate), and/or
+      proxy authentication (i.e., using Proxy-Authenticate).
