If you have WADL/WSDL files with references to external schema files that exist relative to your root file, then you can import/convert them successfully. These files may be accessible by URL or a ZIP file.
Both WADL and WSDL may contain elements that reference external schema files using the
Import tags. If you are converting your file by providing a URL ensure that the schema files exist at a path relative to this file. Alternatively, you can try converting by providing all your relevant files in the form of a ZIP file. This ZIP file must contain both your API description and the schema files.
We currently only support W3C XML Schema files in WADL and WSDL
