;;; Commentary:
;; This package provides an inspector for a WSDL document loaded with
;; `soap-load-wsdl' or `soap-load-wsdl-from-url'. To use it, evaluate:
;; (soap-inspect *wsdl*)
;; This will pop-up the inspector buffer. You can click on ports, operations
;; and types to explore the structure of the wsdl document.
