How many XML gurus does it take to change a light bulb?

Q. How many XML gurus does it take to change a light bulb?

A. Eight:

1 to create a syntax for expressing light bulbs

2 to create broadly similar yet different APIs for interacting with light bulbs

1 to argue that the API differences can be resolved by splitting the 
universe of light bulb applications into
physical-model and logical-model camps.

1 to argue that no single, cohesive model is possible.

1 to disagree and invent yet another "gee! all light bulbs can be though of 
it terms of nodes and arcs" model.

1 to question the sanity of all this and just get stuff working by hacking 
simple lightbulb instances
into relational databases and processing them with Perl.

1 to write the meta-light-bulb joke about it and post it on xml-dev
