I'm pretty sure, though, that you can say definitively that tag soup is *expensive*. Tag soup is the reasons why web browsers need megabytes of code quite a bit of which is reverse-bozo-filters trying to figure out what someone meant when they wrote <math expr=a<b&c<d> or the like. Certain people in the schema-enthusiast camp tend to condemn as "tag soup" anything that hasn't been validated by a schema that is the result of 5 years of committee deliberation, and I have little sympathy. Having said that, I have a lot of sympathy with XML's basic low-level anti-tag-soup rules that require you only to do the right thing with <, >, ", ', =, &, and ;, and pay a pretty big dividend in making software cheaper and especially internationalization cheaper. -Tim
