Lessons that I learned from Michael's quote:
When writing a specification, not all things
need to be specified formally. Don't have
spurious formality. However, there are some
things that need to be specified very rigorously;
for them, do specify them formally.

"Yes, working with the XSD specification is a nightmare; it's the toughest spec I've ever had to work with other than Algol 68, and unlike Algol 68, some of the apparent formality turns out to be spurious; when it gets to tricky things that ought to be formal, like whether two types are identical, the spec bails out."
