No, it is a property name. (cadr src-block) is the plist.

See (info "(elisp) Property Lists")

Any could be made to work, but I'd use (a). Then

: (org-babel-parse-header-arguments
:  (car (plist-get (cadr src-block) :attr_html)))

will give you

: ((:data-external-libs . "http://underscorejs.org/underscore-min.js") 
:   (:class . "list of classes"))

Well, I'd just try it and see.

This is what I use:

* Elisp: (elisp).               The Emacs Lisp Reference Manual.
* Emacs Lisp Intro: (eintr).    A simple introduction to Emacs Lisp programming.

and ample Googling, usually leading to StackOverflow, to get hints on 
stuff I am fuzzy on. And I read docstrings over and over and ...

Best,
