Sure enough, I looked at CoreDocumentImpl and importNode(Node,
boolean, boolean, HashTable), where it deals with DOCUMENT_TYPE_NODE
in the switch statement, and it doesn't copy the internal subset
string from the srcdoctype to the newdoctype. Adding the following
line solves the issue...
newdoctype.setInternalSubset(srcdoctype.getInternalSubset());
I've reported the bug and attached a very simple patch. I hope it
can be applied for the next release!
http://issues.apache.org/jira/browse/XERCESJ-1181
I'm still curious about the Entity node that gets created as a child
of the DocumentType. Is that supposed to get created? Is it necessary?
