build identifier: eclipse3.5.1

we need use the class org.eclipse.birt.report.engine.toc.document.memtreenode when publish our method library to pdf or ms word, but this class hasn't been exported by plugin org.eclipse.birt.report.engine

so could you please export this class?

reproducible: always
is there any issue which stop you to use the interface? the class is internal to engine and may be changed without notice.
we use below classes before in our code:
1. org.eclipse.birt.report.engine.toc.toctree
2. org.eclipse.birt.report.engine.toc.toctreenode

but from we upgrading our product to eclipse 3.5.1, we found the two above classes are no longer available, after some investigations, we use below classes instead:

1. org.eclipse.birt.report.engine.toc.toctree -> org.eclipse.birt.report.engine.toc.tocview
2. org.eclipse.birt.report.engine.toc.toctreenode -> org.eclipse.birt.report.engine.toc.document.memtreenode

but org.eclipse.birt.report.engine.toc.document.memtreenode isn't be exported, that's why i created this bug.

or maybe you have some other good suggestions?

thanks lot!
