<li>The document element (or root element) <em class=rfc2119>MUST</em>
be allowed to be a root element.  <span class=example>For example,
an <code>html</code> element in <code>http://www.w3.org/1999/xhtml</code>

<p><a href="urn:ietf:rfc:4287">Atom 1.0</a> and

<p>However, conformance to some <em class=rfc2119>SHOULD</em>-level
requirements, as well as some informational guidelines, are currently
not checked.  In addition, whether an email-address or a Base64
encoding is correct or not is not checked either.

<p>Use of XML digital signature and encryption is not supported.

<p>The current implementation assumes that there are following 
requirements:</p>
<ul>
<li>Elements and attributes in the Atom namespace, as well as attributes
in the null namespace for an element in the Atom namespace,
<em class=rfc2119>MUST NOT</em>
be used except for contexts where they are allowed by the Atom
