What is currently the best library for working with SOAP in PHP?

Question

PHP

Introductory requirements of the Wishlist (criteria for "better"):
1) Modern library (PSR, tests). Not necessarily popular and full-featured, you need a normal architectural backlog
2) Transparent generation of WSDL from classes
3) A convenient mechanism for casting the generated WSDL to the desired form (data types, complex types), for example, through annotations or configuration
4) Casting incoming parameters to a given type, according to clause 3
5) No binding to any framework
To implement the SOAP protocol (both client and server parts) in PHP, I considered the following options:
1) Zend-SOAP - the existing AutoDiscover (WSDL generator) works rather lousy, it is unrealistic to adapt , you need to write your implementation next to it.
2) BeSimple SOAP - the most interesting functionality is concentrated in the symfony bundle, the general confusion of the code.
Before writing your own implementation or deeply altering an existing one, I want to understand if I missed anything in the solutions considered?

Answer 1

After a lot of research, we implemented our own wrapper over Zend/Soap.
General considerations are as follows:
I hope to publish it in open-source in the near future.
