Smaller interrelated modules that define a complex WSDL structure cannot be correctly edited or validated individually, due to their interdependency with other modules. Oxygen XML Editor provides the support for defining the main module (or modules), allowing you to edit any of the imported/included files in the context of the larger WSDL structure.
You cat set a main WSDL document either using the master files support from the Project view, or using a validation scenario.
To set a main file using a validation scenario, add validation units that point to the main modules. Oxygen XML Editor warns you if the current module is not part of the dependencies graph computed for the main WSDL document. In this case, it considers the current module as the main WSDL document.
