+AT THIS POINT ALL TEXT HAS BEEN COPIED HERE, NOT MOVED.
+DEPENDING UPON HOW THE WG ALTERS THE PROPOSAL BASED ON FEEDBACK, IT MIGHT CHANGE.
+THE 2119 LANGUAGE NEEDS TO BE REMOVED TOO.
+Given that it's from base specs => important to understand, should be moved up before 
+most of the normative sections IMO - renumbering hit again.

+<p>
+While readers, and especially implementers, of LDP are assumed to understand the information in its normative 
+references, the working group has found that certain points are particularly important to understand.
+For those thoroughly familiar with the referenced specifications, these points might seem obvious, yet
+experience has shown that few non-experts find all of them obvious.  This section enumerates these topics; 
+it is simply re-stating (informatively) information locatable via the normative references.

+		Certain specific cases exist where a LDPC server MAY delete a resource and then later re-use the
+		URI when it identifies the same resource, but only when consistent with Web architecture [[WEBARCH]].
+		While it is difficult to provide absolute implementation guarantees of non-reuse in all failure
