| public com.sun.org.apache.xml.internal.dtm.DTM | getDTM(javax.xml.transform.Source source, boolean unique, com.sun.org.apache.xml.internal.dtm.DTMWSFilter whiteSpaceFilter, boolean incremental, boolean doIndexing)Get an instance of a DTM, loaded with the content from the
specified source. If the unique flag is true, a new instance will
always be returned. Otherwise it is up to the DTMManager to return a
new instance or an instance that it already created and may be being used
by someone else.
(I think more parameters will need to be added for error handling, and
entity resolution).
