就理论上来说，这应当能消除互操作性方面的任何问题，因为模式实例定义XML的实际结构，而每个平台负责恰当地处理该XML。
In theory, this should eliminate any problems with interoperability, since the schema instance defines the actual structure of the XML, and it's up to each platform to process that XML as appropriate.
尽管这个办法理论上可行，但显然在实际操作上还有许多问题需要解决。
The idea is sound in theory, but there are evidently still some wrinkles to be ironed out in practice.
如果我们能检测到并解释出这些电信号，这个论点就证毕了。理论上没有理由认为他们只能操纵思考者身体而不能操作其他物体。
If these electrical signals could be detected and interpreted, the argument goes, there is in principle no reason why they could not be used to steer objects other than the thinker's own body.
