+newtag396 fire,+<a+href="foobar.html">foobar</a>,+<img+src="foo.jpg"+/>
+
+So this request is trying to add 3 tags to biblio #396. The CGISESSID is the same as that the browser would
+typically communicate using cookies. If it is valid, the server will split the value of "newtag396" and
+process the components for addition. In this case the intended tags are:
+ fire
+ <a+href="foobar.html">foobar</a>
+ <img src="foo.jpg" />
+
+The first tag is acceptable. The second will be scrubbed of markup, resulting in the tag "foobar".
+The third tag is all markup, and will be rejected.
