Include external parameter entities and the external DTD subset. By default, the two will simply be concatenated, but the namespace-sep core property allows the application to specify a delimiter string for separating the URI part and the local part. A true value for this feature allows the encoding of the file to be specified as a Java encoding name as well as the standard ISO encoding name. Be aware that other parsers may not be able to use Java encoding names. If this feature is set to false, an error will be generated if Java encoding names are used.
Stops parse on first fatal error.
Build the grammar but do not use the default attributes and attribute types information it contains. Ignore the external DTD completely. Full DOM node expansion. If this feature is set to true, the DOM nodes in the returned document are expanded as the tree is traversed. This feature allows the parser to return a document faster than if the tree is fully expanded during parsing and improves memory usage when the whole tree is not traversed.
