/**
* Represents a parser configuration. The parser configuration maintains
* a table of recognized features and properties, assembles components
* for the parsing pipeline, and is responsible for initiating parsing
* of an XML document.
* <p>
* By separating the configuration of a parser from the specific parser
* instance, applications can create new configurations and re-use the
* existing parser components and external API generators (e.g. the
* DOMParser and SAXParser).
* <p>
* The internals of any specific parser configuration instance are hidden.
* Therefore, each configuration may implement the parsing mechanism any
* way necessary. However, the parser configuration should follow these
* guidelines:
* <ul>
* <li>
* Call the <code>reset</code> method on each component before parsing.
* This is only required if the configuration is re-using existing
* components that conform to the <code>XMLComponent</code> interface.
* If the configuration uses all custom parts, then it is free to
* implement everything as it sees fit as long as it follows the
* other guidelines.
* </li>
* <li>
* Call the <code>setFeature</code> and <code>setProperty</code> method
* on each component during parsing to propagate features and properties
* that have changed. This is only required if the configuration is
* re-using existing components that conform to the <code>XMLComponent</code>
* interface. If the configuration uses all custom parts, then it is free
* to implement everything as it sees fit as long as it follows the other
* guidelines.
* </li>
* <li>
* Pass the same unique String references for all symbols that are
* propagated to the registered handlers. Symbols include, but may not
* be limited to, the names of elements and attributes (including their
* uri, prefix, and localpart). This is suggested but not an absolute
* must. However, the standard parser components may require access to
* the same symbol table for creation of unique symbol references to be
* propagated in the XNI pipeline.
* </li>
* </ul>
