I like the idea of a declarative way to support autosuggestions
OpenSearch already made a successful specification supported by most browsers

The datalist element may support dynamic content

The <datalist> element could support a template attribute similar to the one of OpenSearch

<label for="country_name">Country : </label>
<input id="country_name" name="country_name" type="text" list="suggestions" />
<datalist id="suggestions" template="http://myserver.com/suggestions.php?firstChars={value}"></datalist>

The response format should then be specified
In OpenSearch, the suggestions are all links with labels and sometimes descriptions. They can be returned as Atom, RSS, or HTML/XHTML depending of the requested MIME type.

The User-Agent should support at least a plain text response in which each suggestion is on a separated line.
These lines may or not contain HTML tags

It would quite logic to expect a response which would be a set of <option> elements as expected in the content of static <datalist> elements

We may also define specific  MIME types like "application/datalist+xml" and "application/datalist+json"
