Specify schemaLocation in a different folder for Schema

Hello All,
I have a question on defining XML Schema in wMIS with include. Suppose I have this include to address.xsd but it’s in a different folder at the same level as the main xsd.

Main Schema:
ipo.xsd ==> location folder MAIN
address.xsd ==> location folder TEST

That would work if address.xsd is in the same folder as ipo.xsd.
How do I specify or construct the location of address.xsd correctly in TEST folder?

Please advise.

Thank you!
