[Xen-devel] How to handle missing create.dtd in tools/python/xen/xm/xenapi_create.py?

[Stephan Peijnik <spe@xxxxxxxxx>]

Whilst writing my patch to replace the PyXML based XML validation code
in xenapi_create.py I noticed that the old code did not handle a missing
create.dtd file at all.

My patch (see [0]) now issues a warning when create.dtd is missing, but
I would like to know how we want to handle that case? 
Is issuing a Python warning enough or should we bail out with an error?
create.dtd should usually not be missing in xen installations, but the
Debian xen 4 package [1], in version 4.0.1-1, for example does not
include the create.dtd file and thus the validation will not be carried
out.

Any other ideas on handling this? Is this a packaging bug or can
create.dtd be omitted in xen installations?

Regards,

Stephan
