文档貌似有问题

http://dubbo.apache.org/zh-cn/docs/user/demos/subscribe-only.html
http://dubbo.apache.org/zh-cn/docs/user/demos/registry-only.html

这两个貌似写反了

Compare the documentation at the subscribe-only and registry-only URLs named in the issue, along with the attached screenshot. First verify which page descriptions or labels are reversed, then update the corresponding documentation pages so each title and explanation matches its demo. Done means the two pages consistently describe their intended modes.
