And then there's translations into Plain English.

I saw a recent post on XMLSchema-dev where someone quoted the spec:

> In the Rec it says that when namespace="##other", the {namespace

This caused me a moment of panic, as I'm mentally stringing together two
NAND gates and wonder why I have only two inputs when I should have three,
and how I could be digging through the XML Schema spec for two years now and
not notice that they were using boolean NAND expressions in some of the
conditional clauses of the spec, and wondering if all spec writers routinely
use such expressions when explaining thorny conditional dependencies.

Then I looked at the reference:
http://www.w3.org/TR/xmlschema-1/#declare-openness

Ah, never underestimate the power of italics...
