xml schema - validation of ip address against netmask
I am trying to validate the ip address of an interface (as an element 
under the Schema definition) against the netmask value(as an attribute) :
like here:

<addr type="ïpv4" netmask="255.255.255.0">192.168.1.1</addr>

now this is a line in the xml file and i need to validate the ip address 
against the subnet mask.

like       ip:    192.168.1.1   -  class C
 netmask:    255.255.255.0      - valid for class C
 netmask:    255.255.255.255  -not valid for class C



how should i achieve it ?? i want to validate this process in my xml 
schema document itself.
