paper 'A More Canonical Form of Content MathML to Facilitate Math Search'

Hello www-math,

At Extreme Markup 2007, there was a very interesting paper by Moody E. Altamimi and Abdou S. Youssef: 'A More Canonical Form of Content MathML to Facilitate Math Search'

http://www.idealliance.org/papers/extreme/proceedings/html/2007/Altamimi01/EML2007Altamimi01.xml

I just wanted to bring this to the attention of the Math WG.
