Fixed some bugs in this file.

Implementation for the interface.

Add a new client interface with string type for web service.

in toxml method, add new code to handle dtd.

Add a new constructor to hanlde DTD node.

Add code to handle public id and system id.

Implement logout method.

Add a logout method.

Implemented the update and delete methods in the interface, along with tests.

Implemented the "insert()" method and wrote a test to test it. The new test
depends on the property "newdocid" be set to something unique in the build.xml
file so that the insert will work properly. Probably need to fix this to be
some kind of autoincrement counter or random number so that it can be run...
