How do you propose to organise it instead? The XML, HTML, and CSS 
specifications quite clearly show that organising it so that the syntax 
and the parsing rules are defined in the same prose leads to serious 
deficiences (HTML forgot to define parsing altogether, CSS failed to 
give a number of error handling rules, and XML doesn't define how you 
get a tree from the markup).
