Interesting, but completely understandable. I am assuming you mean SMIL,
not SML - SML is a programming language to the best of my
knowledge. Parsing that I have done is always slower on data that contains
more attributes, CDATA and content, probably as a result of the in-memory
structures that need to be created as these portions are discovered.
I advocate, from our experience parsing every sort of document imaginable,
the use of simple, non-cryptic XML with as few attributes as needed. I
find attributes add weight to even an event based parse.
