Specify whether to document the form of the attribute name 
(i.e. if it should be namespace-qualified or not).
<p>
All globally declared attributes have namespace-qualified names.
<p>
For locally declared attributes, their namespace qualification is specified by the <b><code>'form'</code></b>
attribute of the attribute component. When that attribute is absent, its default value is defined by the
<b><code>'attributeFormDefault'</code></b> attribute of the parent <b><code>&lt;xs:schema&gt;</code></b>.
<p>
<u>Possible Choices</u>:
<p>
<i>"any"</i>
<dl><dd>
Document the namespace-qualified form for all attribute components (both global and local ones).
</dd></dl>

<i>"non-default only"</i>
<dl><dd>
Document the namespace-qualified form only for locally defined attribute components with the explicitly
specified <code>'form'</code> attribute. (No default value of that attribute will be documented.)
</dd></dl>

<i>"none"</i>
<dl><dd>
Do not document the namespace-qualified form of the attribute.
</dd></dl>
