* external entities (including the external DTD subset and external parameter
* entities) before including them.</p>
*

* will be especially useful for applications that build XML documents from
* databases or other specialized input sources, or for applications that use
* URNs.</p>

/**
* Allow the application to resolve external resources.
*
* The <code>DOMLSParser</code> will call this method before opening any external resource,
* including the external DTD subset, external entities referenced within the DTD, and
* external entities referenced within the document element (however, the top-level
* document entity is not passed to this method). The application may then request that
* the <code>DOMLSParser</code> resolve the external resource itself, that it use an
* alternative URI, or that it use an entirely different input source.
*
* Application writers can use this method to redirect external system identifiers to
* secure and/or local URI, to look up public identifiers in a catalogue, or to read
* an entity from a database or other input source (including, for example, a dialog box).
*
* The returned DOMLSInput is owned by the DOMLSParser which is
* responsible to clean up the memory.
*
* @param resourceType The type of the resource being resolved. For XML [XML 1.0] resources
* (i.e. entities), applications must use the value "http://www.w3.org/TR/REC-xml".
* For XML Schema [XML Schema Part 1], applications must use the value
* "http://www.w3.org/2001/XMLSchema". Other types of resources are outside
* the scope of this specification and therefore should recommend an absolute
* URI in order to use this method.
* @param namespaceUri The namespace of the resource being resolved, e.g. the target namespace
* of the XML Schema [XML Schema Part 1] when resolving XML Schema resources.
* @param publicId The public identifier of the external entity being referenced, or <code>null</code>
* if no public identifier was supplied or if the resource is not an entity.
* @param systemId The system identifier, a URI reference [IETF RFC 2396], of the external
* resource being referenced, or <code>null</code> if no system identifier was supplied.
* @param baseURI The absolute base URI of the resource being parsed, or <code>null</code> if
* there is no base URI.
* @return A DOMLSInput object describing the new input source,
* or <code>null</code> to request that the parser open a regular
* URI connection to the resource.
* The returned DOMLSInput is owned by the DOMLSParser which is
* responsible to clean up the memory.
* @see DOMLSInput#DOMLSInput
