With all due respect, I disagree that a DSL is useful for this
purpose. In fact, I would disagree with DSLs in most cases, especially
if its supposed to be used for programming. The reason for this is
that creating a good language is much more harder than creating a
language, and such efforts tend to end up with crappy languages.
Your concern is valid, but I think you are underestimating the amount
of effort already being put into creating platform-neutral DSLs for
business, law and finance. Hint: an XML schema is a declarative
specification of a DSL, albeit one with terrible, human-antagonistic
syntax. Even the SEC document contains such a thing already, as Anand
quoted in an earlier email in this thread. Here are some other examples:
http://www.oasis-open.org/committees/tc_cat.php?cat=lawgov
http://www.legalxml.org/
http://www.service-architecture.com/xml/articles/finance_xml.html
http://www.omg.org/technology/documents/br_pm_spec_catalog.htm
What all these share in common is lack of human-friendly concrete
syntax. That is the real problem to be solved, but it remains to be
seen who will solve it and whether the vendors of eye-wateringly
expensive middleware have the motivation to do so.
