 The created GraphQL schema contains all types declared in the WSDL and provides all operations of
 the SOAP endpoint as GraphQL mutation fields. This enables you to re-publish a SOAP endpoint as a

 This package is fully dependend on the [node-soap package](https://github.com/vpulim/node-soap). It
 will only work in a Node.js environment.

-## Limitations and Issues
-
-### Supported WSDLs
-
-There is no guarantee that this package will work with every valid WSDL.
-
-[node-soap-graphql.spec](spec/node-soap-graphql.spec.ts) lists SOAP endpoints that were tested with
-this package. It also shows how to configure custom behavior for SOAP endpoints.
-
-Feel free to post an issue (or better yet: create a pull request with a test case) if this package
-does not work with your SOAP endpoint.
-
-### XSD features
-
-WSDL, and especially the XSD-based schema section,
-[allows a wide variety of options to define primitive types](https://www.w3.org/TR/xmlschema-2/#built-in-datatypes).
-Handling of these options are only implemented in the most basic way;
-[see `DefaultTypeResolver`](src/soap2graphql/custom-type-resolver.ts).
-
-In most cases you can handle the specifics of your SOAP endpoint by implementing a
-[`CustomTypeResolver`](src/soap2graphql/custom-type-resolver.ts).
