Sybase ASE - xmlvalidate with xml schema - xsd

Question

I receive inputs to a procedure as xml and I've prepared the xml schema and would like to validate the input with the schema and throw an error if the input doesn't comply. I am trying to use xmlvalidate() option 'schemavalidate=yes' but couldn't figure out where to store my xml schema. The examples indicate a http url as the xml schema but should I host my xml schema? or should I store it as a database "text" column? Could someone guide me how to store and use the xml schema to use xmlvalidate()? We are at Sybase ASE 15.7
Appreciate your help!
Just adding the below question as hurdled in my next step on this:
I've hosted my xml schema and trying to use xmlvalidate as below:
xmlvalidate(#purgeTableInfo, option 'schemavalidate=yes, nonamespaceschemalocation="http://myhost:5000/purgeschema"')
The required access to this purge schema has been provided to the unix box/login that hosts the database. We are able to ping to "myhost" from the unix box on which sybase is running. But, I am still getting the below error.
"XMLVALIDATE(): XML parser fatal error <<An exception occurred!
Type:NetAccessorException, Message:Could not create the socket for URL
'{0}'. Error={1>> at line 0, offset 0.
Sybase error code=14702
Severity Level=16, State=0, Transaction State=0"
Does anyone know what would be the reason and how should I go about fixing this?
Any help on this would be great!

According to the documentation, to validate against a dtd, your schema needs to be hosted. Your xml should be stored in a text column in the database, not your xml schema. There are a number of examples in the documents, which should guide you in the right direction.
