XMLSchema validation error in Tuscany Logging Policy

[黄勇]

大家好！

想请教大家一个关于 Tuscany 的问题，具体问题如下：

我用的是 1.6.2 版本，做了一个 Calculator Policy 的示例，我试了一下 logging 特性，发现虽然执行成功了，但出现了以下严重错误：

严重: XMLSchema validation error occured in: null ,line = 5, column = 13, Message = cvc-complex-type.2.4.a: Invalid content was found starting with element 'operation'. One of '{WC[##other:"http://www.osoa.org/xmlns/sca/1.0"]}' is expected.

以下是我的 Calculator.composite 文件：

<?xml version="1.0" encoding="UTF-8"?>
