Since different browsers support different CSS selectors, it seems necessary to provide a way to indicate which selectors can actually be used by querySelector() and querySelectorAll(). Something along the lines of supportsSelector() that returns true if a certain type of selector is available and false if not, perhaps? Just to throw something out for a debate:
Due to the lack of compelling use cases provided in this thread and failure to come up with a reasonable solution that actually solves any real problems, I have decided not to include such a feature in the spec at this time.
If in the future, based on experience with the current API, we discover use cases that would benefit from such a proposal, then we can certainly revisit it then and find an appropriate solution.
Please let me know whether or not you are satisfied with this response. -- Lachlan Hunt - Opera Software http://lachy.id.au/ http://www.opera.com/
