Can I have one XML Schema (XSD) include another XML-Schema?
I currently have two XSD schemes and one is a "light" version of the other. Right now I have everything in the "light" version repeated in the "complete" schema, but this becomes a pain when I need to make a change, and it goes against the DRY principle anyways, so I was wondering if there was an element that served to include another schema into a schema, so I can have my "complete" inherit from the "light" schema to reduce maintenance hurdles.
There are two methods for this.
<xsd:include schemaLocation="pathToFile" /> should be used for including files of the same namespace.
<xsd:import namespace="namespace" schemaLocation="pathToFile" /> should be used for include files in a different namespace. Usually you will specify the namespace given as the targetNamespace of the imported schema.
Use the <include> element, see for example here.
