The underlying question is: why do you want to use an 'f' representation of a floating point value rather than a 'g' representation?
If I read the XML Schema specification correctly, then an xs:double value is allowed to be in scientific notation, so there should be little reason to output this value in a different representation. A reader of said XML document should be able to parse and handle that value with little trouble. Think of the XML document as a transport format, where a client is going to do its own internal representation. Generally speaking, it is often good to think twice before changing a stdlib function in a way that cannot be added into the Go repository. You will have to maintain that yourself, and it is brittle since the next release will surely change it back. It is probably better to look for a way to do custom formatting of a floating point value in your case. Although I'd much rather leave it in scientific notation, were it me.
