<p>Attempt to apply the value as a new instance of the particle's
term.</p>
<p>The <a href="pyxb.binding.content.ContentState_mixin-class.html"
class="link">ContentState_mixin</a> created for the particle's term is
consulted to determine whether the instance can accept the given value.
If so, the particle's maximum occurrence limit is checked; if not, and
the particle has a parent state, it is informed of the failure.</p>
<dl class="fields">
<dt>Parameters:</dt>
<dd><ul class="nomargin-top">
<li><strong class="pname"><code>instance</code></strong> - An instance of a subclass of {basis.complexTypeDefinition}, into
which the provided value will be stored if it is consistent with
the current model state.</li>
<li><strong class="pname"><code>value</code></strong> - The value that is being validated against the state.</li>
<li><strong class="pname"><code>element_use</code></strong> - An optional <a href="pyxb.binding.content.ElementUse-class.html"
class="link">ElementUse</a> instance that specifies the element
to which the value corresponds. This will be available when the
value is extracted by parsing a document, but will be absent if
the value was passed as a constructor positional parameter.</li>
</ul></dd>
<dt>Returns:</dt>
<dd><code>( consumed, underflow_exc )</code> A tuple where the first
element is <code>True</code> iff the provided value was accepted
in the current state. When this first element is
<code>False</code>, the second element will be <code>None</code>
if the particle's occurrence requirements have been met, and is
an instance of <code>MissingElementError</code> if the observed
number of terms is less than the minimum occurrence count.
Depending on context, the caller may raise this exception, or may
try an alternative content model.</dd>
<dt>Raises:</dt>
<dd><ul class="nomargin-top">
<li><code><strong class='fraise'><a href="pyxb.exceptions_.UnexpectedElementError-class.html">pyxb.UnexpectedElementError</a></strong></code> - if the value satisfies the particle, but having done so exceeded
