#15 Schema schema.xml not found

I have tried to build your "input" example:
http://ajaxforms.sourceforge.net/samples/input.html#

I downloaded both xform and xml files and put them in web/ directory. It built without error or warning but once in the browser the message "Schema schema.xml not found" is displayed. I tested with Firefox, ie and Epiphany.

This is really strange; is it a regression from a previous version? What can I do?

Thanks
