Layer Cake

Layer Cake
You're looking at a new standard, lot's of XML
and XML schemas. You take the finalized standard
out in the world, you take even more XML. You
climb a little higher, you take less XML. Till
one day you're up in the rarefied atmosphere and
you've forgotten what XML even looks like.
Welcome to the layer cake.
Details, details. Things to do, things to get
done. Don't bother me with details. Just tell me
when they're done.
Know and respect your standard.
We've gotta test the "snap, crackle and pop"
factor on these.
I'm not a gangster, just a developer. And my
commodity happens to be code.
Always work in teams.
