<h2>Definition and Usage</h2>
<p>The any element enables the author to extend the XML document with elements
not specified by the schema.</p>
<h3>Element Information</h3>
<ul>
<li><b>Parent elements:</b> choice, sequence</li>

<p>(The ? sign declares that the element can occur zero or one time inside the any element)</p>
<table class="ws-table-all notranslate">
<tr>
<th>Attribute</th>
<th>Description</th>

<tr>
<td>id</td>
<td>Optional. Specifies a unique ID for the element</td>
</tr>
<tr>
<td>maxOccurs</td>
<td>Optional. Specifies the maximum number of times the any
element can occur in the parent element. The value can be any number >= 0,
or if you want to set no limit on the maximum number, use the value
"unbounded". Default value is 1</td>
</tr>
<tr>
<td>minOccurs</td>
<td>Optional. Specifies the minimum number of times the any
element can occur in the parent element. The value can be any number >=
0. Default value is 1 </td>
</tr>
<tr>
<td>namespace</td>
<td>Optional. Specifies the namespaces containing the elements
that can be used. Can be set to one of the following:<ul>
<li>##any - elements from any namespace is allowed (this is default)</li>
<li>##other - elements from any namespace that is not the namespace of the
parent element can be present</li>
<li>##local - elements must come from no namespace</li>
<li>##targetNamespace - elements from the namespace of the parent element
can be present</li>
<li>List of {URI references of namespaces, ##targetNamespace, ##local} -
elements from a space-delimited list of the namespaces can be present</li>
</ul>
</td>
</tr>
<tr>
<td>processContents</td>
<td>Optional. Specifies how the XML processor should handle
validation against the elements specified by this any element. Can be set to
one of the following:<ul>
<li>strict - the XML processor must obtain the schema for the required
namespaces and validate the elements (this is default)</li>
<li>lax - same as strict but; if the schema cannot be obtained, no errors
will occur</li>
<li>skip - The XML processor does not attempt to validate any elements
from the specified namespaces</li>
