+    # == Description
+    #
+    # Creates a new URI::WS object from components, with syntax checking.
+    #
+    # The components accepted are userinfo, host, port, path, and query.
+    #
+    # The components should be provided either as an Array, or as a Hash
+    # with keys formed by preceding the component names with a colon.
+    #
+    # If an Array is used, the components must be passed in the
+    # order <code>[userinfo, host, port, path, query]</code>.
+    #
+    # Example:
+    #
+    #     uri = URI::WS.build(host: 'www.example.com', path: '/foo/bar')
+    #
+    #     uri = URI::WS.build([nil, "www.example.com", nil, "/path", "query"])

+    # invalid WS URIs as per RFC 1738.

+    #
+    # == Description
+    #
+    # Returns the full path for a WS URI, as required by Net::HTTP::Get.
+    #
+    # If the URI contains a query, the full path is URI#path + '?' + URI#query.
+    # Otherwise, the path is simply URI#path.
+    #
+    # Example:
+    #
+    #     uri = URI::WS.build(path: '/foo/bar', query: 'test=true')
+    #     uri.request_uri #  => "/foo/bar?test=true"
