"Data blocks" syntax specification draft

[Mikhail V]

I have made up a printable PDF with the current version
of the syntax suggestion.

After some of your comments I've made some further
re-considerations, e.g. element separation should
be now much simpler.
A lot of examples with comparison included.


Comments, suggestions are welcome.
