The talk I gave was specific to making analysis of guaranteed
streamable constructs easier by using 10 rules of thumb for XSLT
stylesheet programmers. These rules cover between 80 and 100% of your
needs, depending on the complexity of your scenario. For those cases
that are not covered, my paper contains a full flowchart of all steps
of guaranteed streamability analysis (and my slides contain an
instructional example of how to use them).

The proceedings are freely available at http://xmlprague.cz
(proceedings of 2014, PDF is currently linked from the homepage, but
this will change over time). The Powerpoint slides and a one-page
version of a flowchart that can be used for understanding
streamability (a work in progress as long as the standard is not
finalized) will remain available through http://exselt.net/papers.
