Answer 1

In short (full story provided by links in the splash's answer):

{$RTTI EXPLICIT METHODS([]) PROPERTIES([]) FIELDS([])}

Note that as of XE6 and newer, this needs to be in each individual unit for which you want to disable RTTI. Before that (XE5 and below) it could be in the DPR file and would apply to all units in the project.
