Effective XML has been published on Safari. Safari subscribers can now read it in its entirety online.

Meanwhile Tech Book Report has published another nice review of Effective XML, and it's jumpoed way up in the Amazon rankings since the Slashdot review came out. Check it out if you haven't already.

The W3C Math Working Group has published three notes:

Bound Variables in MathML

"Bound variables are central representational primitives in mathematical languages. They allow one to express functions, quantification, and operators with qualifiers. The first edition of the MathML 2.0 Recommendation [MathML2] was somewhat vague about the identity conditions on bound variables, and as a consequence Content MathML applications were left to guess the exact meaning. This Note provides some of the rationale behind how this has been clarified in the second edition"

Structured Types in MathML 2.0

"This Note discusses the facilities that are available in the MathML 2.0 Recommendation to facilitate the capturing of mathematical type information. It demonstrates how a combination of these features can be systematically used to provide support for general mathematical types."

Units in MathML

"MathML is an XML application for describing mathematical notation, capturing both its structure and content. As such, its scope does not extend to include units - determinate quantities adopted as standards of measure - which nevertheless, by their very nature, occur in an applied mathematical setting. This Note makes recommendations and suggestions for how units can be incorporated into MathML."
