[xml] xmllint DTD question

[Alistair Leslie-Hughes <leslie_alistair hotmail com>]

Hi,

Load this attached file with libxml gives the following our
I/O warning : failed to load external entity

using xmllint
xmllint --valid --noout room1.xml
room1.xml:2: validity error : Validation failed: no DTD found !
<wpkg >
       ^

The file doesn't specify a DTD so why is it trying to look for one?

Best Regards
  Alistair Leslie-Hughes
