The notation ws* is introduced but not defined. As section 2.1 table 1 says 
zero or more will be noted with curly braces, it would probably make more sense 
to use {ws} instead of ws*. SImilarly for nl* in the section 2.2 above.
I am not sure how to define a Qualifier. Maybe something along the lines of "A 
Qualifier expresses a relationship between the object of the annotation and a 
well-defined semantic entity." from 
http://code.google.com/p/annotation-ontology/wiki/Qualifiers

Maybe having an example of OBO file with different elements examplified and 
named would help? Maybe as an annex to the spec?

ws issue fixed. I've tried to avoid giving too much semantics in the syntax section. Qualifiers are really a mixed bag. Sometimes they are axiom annotations, sometimes they alter the semantics of the tag in which they are embedded (e.g. cardinality). But even just saying something like "qualifiers can represent axiom annotations" means we have to get into axioms and annotations in the OWL sense... Examples for each of the sections would be a good idea. I'll leave this issue open for now.
