This is my first reading of this doc. The formatting improvements look good. A definite enhancement. Review contains a few comments. My main difficulty is separating creation of a proxy instance from use of a proxy instance. Some of the creation parameters govern the use, and hence do not make must sense until one reads the instance description a few paragraphs further on. Perhaps the initial sentence "A :class:`ServerProxy` instance is an object that manages communication with aremote XML-RPC server." should be expanded into a paragraph with some of the description given later.
Thank you for your review Terry. Updated patch addresses most of your comments. But I'm unable to expand ServerProxy description as you suggest. May you can do this? My purpose was modest. Just fix some incorrect and outdated sentences. Then I fixed some formatting. I was not going and is not able to do anything besides this. I will take all that you offer.
