Read it carefully, but don't get frightened by it: most of the differences are things that very few stylesheets would ever do deliberately. You can do the conversion in one step or two. The two-step approach is Step 1: switch to an XSLT 2.0 processor, leaving your stylesheets saying version="1.0" Step 2: change the version attribute to say version="2.0". In the intermediate stage you are running XSLT 2.0 in XSLT 1.0 mode, which causes some constructs to behave in a backwards-compatible way, for example $a < $b converts both values to numbers rather than comparing them as strings (that's probably one of the biggest incompatibilities). Personally, I'd be inclined to do it in a single step, because it gets the job over with. > I have found on the > web that XSLT2.0 is too Saxon specific. Is that true?.
