While the timbre of the E♭ tubax is more focused and compact than that of the full-sized contrabass saxophone.
Currently there is no good way to parse XML and other markup languages with Clojurescript. There are no Clojurescript-based libraries and most of the Javascript ones require access to the DOM.
This last point is critical because HTML5 Web Workers don't have access to these APIs so an alternative is necessary.
Also we're aiming to be fully compatible with the clojure.xml format so we can use helping functions inside the Clojure library.
Tubax uses behind the scenes sax-js a very lightweight library for for XML parsing based on SAX (simple api for xml).
