Yes, send it to fdo-internals. I can ask one of XML knowledgeable developers to review it. If it looks OK we can apply it to the trunk. The option of a patch against a previous release is also an option.

That was a bit hasty. It turned out my replication example was falling foul of the stack issue before it had a chance to exhaust heap space. With the stack issue dealt with a I get a memory exhaustion problem that can be fixed by tweaking the code to FdoXmlFeatureReaderImpl::ReadNext so that it releases features which aren't needed any more.

I'm not quite sure what I'm going to do with this, but if I wanted to submit a patch for consideration for the next release of FDO, what's the etiquette?
Is this something I should ask about on the 'internals' list?
