In practice with tools implemented this way there is usually little
semantic checking, so typos such as incorrectly spelt attributes are
not detected and the Wrong Thing happens.

Tools with more integrated semantic checks (typical with yacc :) don't
have this problem.

If you use TCL, please validate input carefully.
