The primary trade-off is between Type Suggesting vs. Role Suggesting parameter names. For example, aString and aSymbol tell us only what type of object the parameter expects, while aName and aTitle tell us the *role* (or purpose) of the parameter, with the expected type hopefully obvious. You

Are you developing in Squeak? I ask because the XML parser in the default Squeak image is very old. You can download the latest Pharo XMLParser lib from the SqueakMap. It's the "XMLParser" project. Other libs I maintain are also available as SM projects, like "XMLParser-XPath". If you're doing
