404 # How to manage theorys in subproblems wrt. the requirement, #

406 #############################################################################
408 eg. 'Script Solve_rat_equation' calls 'SubProblem (RatEq',..'
409 which would not allow to 'solve (y'' = -M_b / EI, M_b)' by this script
410 because Biegelinie.thy is subthy of RatEq.thy and thus Biegelinie.M_b
411 is unknown in RatEq.thy and M_b cannot be parsed into the scripts guard
414 Preliminary solution:
415 # the thy in 'SubProblem (thy', pbl, arglist)' is not taken automatically,
416 # instead the 'maxthy (rootthy pt) thy' is taken for each subpbl
417 # however, a thy specified by the user in the rootpbl may lead to
418 errors in far-off subpbls (which are not yet reported properly !!!)
419 and interactively specifiying thys in subpbl is not very relevant.
421 Other solutions possible:
422 # always parse and type-check with Thy_Info.get_theory "Isac"
423 (rejected tue to the vague idea eg. to re-use equations for R in C etc.)
424 # regard the subthy-relation in specifying thys of subpbls
425 # specifically handle 'SubProblem (undefined, pbl, arglist)'
