          Order of query params is not important. The 'str'
          and 'lke' query parameters are optional.
pattern : an SQL 'like' pattern matching any stereotype that
          starts with it.
descript: removes the stereotypes specified by 'str' and / or
          'lke' query parameters. If no 'str' and 'lke' query
          parameters exist, all stereotype records will be
          deleted. Referential integrity constraints will cause
          records of tables where those stereotypes are foreign
          keys to be removed as well. This means that deleted
          stereotypes will cease to have any profiles (features),
          and that user references to deleted stereotypes will
          also be lost. Can be used to initialize the Stereotype
          Mode DB, by deleting all records from all tables. In
          order to delete the profile (features) of a stereotype
          without affecting the user references to that stereotype,
          the 'remftr' command can be used. If the specified
          stereotypes are not found, no records will be deleted
          (200 OK will still be returned). If the error code 401
          is returned then no record has been deleted.
example : ster?clnt=name|pass&com=remstr&str=visitor&str=experienced
          ster?clnt=name|pass&com=remstr&str=visitor&lke=exper
          ster?clnt=name|pass&com=remstr   (deletes all records from all tables)
returns : 200 OK, 401 (fail, request error), 501 (fail, server error)
200 OK  : in this case the response body is as follows
          <?xml version="1.0"?>
          <?xml-stylesheet type="text/xsl" href="/resp_xsl/rows.xsl"?>
          <result>
          <row><num_of_rows>number of relevant rows</num_of_rows></row>
          </result>
comments: the reference to the xsl file allows to view results
          in a web browser. In case the response body is handled
          directly by an application and not by a browser, this
          reference to xsl can be ignored.
