/**
 * 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.
 * 

* 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). *

* 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: *

    *
  • * Call the reset method on each component before parsing. * This is only required if the configuration is re-using existing * components that conform to the XMLComponent 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. *
  • *
  • * Call the setFeature and setProperty 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 XMLComponent * 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. *
  • *
  • * 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. *
