The use of schemaLocation is entirely optional and the Version attribute is incorrect in your instance (unless you have defined an attribute called Version in your schema)

The following instance 

<Service xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://axis.com/service">
any string
</Service>

Validates fine against the schema:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:wmh="http://www.wmhelp.com/2003/eGenerator"
    elementFormDefault="qualified"
    targetNamespace="http://axis.com/service"
    xmlns="http://axis.com/service"
    version="1.0">
  <xs:element name="Service" type="xs:string"/>
</xs:schema>

All I did was replace your type AxisServiceType with a string.

In order to determine the exact cause of the failure you are having I would need to see your entire schema and instance document.
