Just wonder what the yl stands for inside name of HP switch name OR what is the main difference between a switch with yl and without?

I don't think the series letters stand for anything in particular, but they indicate the series of switch and the compatibility of modules for the chassis-based switches (and the build of the ProCurve software contains the same features). To my knowledge, the only switches which actually match series letters are 5400/8200 - the rest all seem to have their own slot type.
I don't think I've seen an official FAQ on this - this is just what I've inferred over the years.

The 2 letter suffix were just part of the model groupings. There may have been a definition released at some point, but I don't ever recall seeing it.
3500/6200yl <-- they share the same modules
5400/8200zl <-- they share the same modules
2910al (note the alphabetic increment)
The new switches (eg 2920) don't have a suffix any more.
