[xsde-users] Fwd: Unwanted validation

[James Sutton]

- just a quick update..
The hand-edited code (removed parsers to read only the title) does work now and is 4X faster, which is a great help

Thanks
James

Is this going to work or am I wasting my time? At the moment the validator is complaining and refusing to read the file at all, but this could be because I have made an error. I can't help feeling that if I remove parsers it's going to think that unparsed elements must be invalid, so this approach is doomed.
