given in the grammar for the <code class="literal">Authorization</code>

header. The grammar requires that the <code class="literal">qop</code>

however one widely deployed server implementation
|

(Microsoft® IIS 5) rejects the request if these parameters

are not quoted. neon sends these parameters with

quotes—this is not known to cause any problems with

other server implementations.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2926956"></a>Namespaces in XML</h3></div></div></div><p>The neon XML parser interface will accept and parse
