IRI is a sequence of Unicode characters that has a special meaning. Like 2010 or 3,1415. For instance PI, and all real numbers, have a special separator character which is the comma. And real numbers have a special internal structure (or syntax) that allow for interpreting them following a logical mental path. That syntax could be summarized in two rules : 1- real numbers must be presented visually ordered LTR beginning with the highest end and ending with the lowest end. Regardless of the directionality of the overall context 2- the integer part must be on the left side of the comma separator and the fractional part must be on the right side of the comma. Regardless of the directionality of the overall context I think those rules are IRI dependent and are outside the scope of Unicode. The only way for unicode to handle this kind of rules is to have an extensibility mechanism which allows for adding new specs for new notations. Something like what is done at IETF for URI schemes.
