備註

屬性通常是 URI， Action 表示 SOAP 要求的意圖。 不過，SOAP 規格不會限制格式，以及 URI 是否參考現有的檔。 Web 服務器可以使用屬性的存在和內容 Action ，例如防火牆，以適當地篩選 HTTP 中的 SOAP 要求訊息。

根據預設，.NET Framework 1.1 版會針對針對 XML Web 服務產生的 WSDL 檔案中每個支援的 SOAP 系結，在 元素的 soap:operation 屬性中發佈 Action 屬性 soapAction 。 支援的 SOAP 系結是 SOAP 1.1。

如需詳細資訊，請參閱 W3C 網站上的 SOAP 規格。
