It is my understanding that Flex is just used for describing the
regular expressions you want to use to match against text to find
tokens. That's not very well written, but by example, in YACC/Bison:

node: NODE L_BRACE children R_BRACE node
         | ;

children: CHILDREN L_BRACKET node R_BRACKET


Were NODE, L_BRACE, R_BRACE, CHILDREN, L_BRACKET and R_BRACKET are the
tokens returned by Flex.

Does that make any more sense? Sorry if I've missed the point and over
simplified the problem.
