Inasmuch as I find it useful and 50% of the people that I’ve shown it to find it useful, the XSL 1.1 Properties quick reference is now available at http://www.mentea.net/resources/xsl11-properties.pdf. It crams all the properties, their values, and their defaults into two A4 pages for when you just want to know the allowed value of a particular property. When printed, it works best when the pages flip along the long edge, and when viewed online, the property names link to their definitions in the XSL 1.1 spec.
