我收集了WSDL中描述的Web服务集合。我想向该文件添加语义以创建如下所示的WSDL-S文件：
<operation name = "checkStatus" pattern="mep:in-out" >
<action element = "rosetta:QueryOrderStatus” />
<input messageLabel = ”statusQuery” element = "xsd:PurchaseOrderStatusQuery" />
<output messageLabel = ”status” element = "xsd:PurchaseOrderStatusResponse" />
</operation>
