XSImplementationImpl

public class XSImplementationImpl extends org.apache.xerces.dom.CoreDOMImplementationImpl implements org.apache.xerces.xs.XSImplementation
Implements XSImplementation interface that allows one to retrieve an instance of XSLoader. This interface should be implemented on the same object that implements DOMImplementation.

public booleanhasFeature(java.lang.String feature, java.lang.String version)
Test if the DOM implementation supports a specific "feature" -- currently meaning language and level thereof.

param
feature The package name of the feature to test. In Level 1, supported values are "HTML" and "XML" (case-insensitive). At this writing, org.apache.xerces.dom supports only XML.
param
version The version number of the feature being tested. This is interpreted as "Version of the DOM API supported for the specified Feature", and in Level 1 should be "1.0"
return
true iff this implementation is compatable with the specified feature and version.

    	
        return (feature.equalsIgnoreCase("XS-Loader") && (version == null || version.equals("1.0")) ||
		super.hasFeature(feature, version));
