The main difference between content and presentation markup is that content
markup is geared towards machine consumption, and therefore has to be
unambiguous (therefore the simpler grammar). Presentation markup is geared
towards consumption by humans, whe can do the disambiguation themselves,
but need visual hints (e.g. spacing,...) for that.
