This only works if the form data is in the format you need it in. Say that you have a calendar-like feature -- if the server uses .../year/month/day/... ...as the URL form, you can't just convert an value into that URL, so you still have to have script or server-side redirection or some logic in the templating language -- and short of making it turing complete, the templating language won't ever be a complete solution.

As I have not always been paid to participate in the standards process, I can say from personal experience that it is quite possible to spend free time doing this if one wants to.

I don't see evidence that there are places that let you do forms and service interaction but don't let you have scripts or server-side scripts.

A script can implement a hard-coded conversion, it doesn't have to implement templating.

Sure, but in this case it's not clear to me we're anywhere near 85%.

If the list of URIs is finite, then there's no need for a form.

HTML4 was focused on a better information system, at the cost of Web apps. HTML5 is just redressing the balance. I imagine going forward that both of these, along with other use cases, will be handled equally. -- Ian Hickson U+1047E)\._.,--,'``.fL http://ln.hixie.ch/ U+263A/, _.. \ _\ ;`._ ,.
