Refactor the HTML element parser
The purpose is to allow attributes to be specified as macro invocations. For example `<div myattr=<<mymacro param1 param3>>>`. The parser needed sprucing up in order to copy with the nesting of angle brackets. The refactoring has been done with an eye on using the same technique in the filter expression parser (which is pretty messy at the moment -- it throws exceptions for syntax errors, which is bad). Later I'm hoping to extend the technique to create a more flexible table parser.
