Receive notification of a skipped entity. This is not called for entity
references within markup constructs such as element start tags or markup
declarations. (The XML recommendation requires reporting skipped external
entities. SAX also reports internal entity expansion/non-expansion,
except within markup constructs.)
<p>
<p>
The Parser will invoke this method each time the entity is skipped.
Non-validating processors may skip entities if they have not seen the
declarations (because, for example, the entity was declared in an
external DTD subset). All processors may skip external entities,
depending on the values of the
<code>http://xml.org/sax/features/external-general-entities</code> and
the <code>http://xml.org/sax/features/external-parameter-entities</code>
properties.
</p>

@param name the name of the skipped entity. If it is a parameter entity,
            the name will begin with '%', and if it is the external DTD
            subset, it will be the string "[dtd]"
@throws org.xml.sax.SAXException any SAX exception, possibly wrapping another exception
