The schema datatypes spec defines a hexBinary format. You can see it
at:
http://www.w3.org/TR/xmlschema-2/#hexBinary
Basically each byte is represented by two ASCII hexadecimal
characters.
It's also common in schemas to represent IP addresses using xs:string
and then restrict that with a pattern along the lines of:
<xs:pattern value="[1-9][0-9]{0,2}(\.[1-9][0-9]{0,2}){3}"/>
You can refine the pattern if you like to take into account that you
don't get IP addresses like 876.432.354.974 , but that's too much like
hard work for me!
HTH,
Pete.
