Re: [alto] Discussion II: Unifying cost-mode and cost-type to a single type

Hi,

As said some time ago, I do support the idea. It is much better structured and simplifies processing (at both sides, I'd say) And it posseses a taste close to the good-ole MIME types I cannot avoiud to appreciate.

Will go through the detailed text later and provide comments (if any) but let's get the ball rolling!

Be goode,
