[xml/sgml-pkgs] Bug#575770: xml-core: added "dh $@ --with xml-core" support

[Joseph Herlant]

Control: tags -1 = patch pending

Hi,

I tested the script by installing it and created a dummy package
containing only the "schema" folder of xml-core + the "*.xmlcatalogs"
file and the "--with xml-core" works now perfectly.

Added an example section in the documentation of dh_installxmlcatalogs
using this option.

The new file is installed using debian/xml-core.install

It will be available in 0.13+nmu3 that will be uploaded in the next few days.

Best regards,
Joseph
