<link rel=style href="[uri]" type="[notation]">
The notation-string could also have a defined syntax, e.g.:
This would then look something like:
<link rel=style href="format.css" type="CSS//1.0">
<link rel=style href="format.css2" type="CSS//2.0">
<link rel=style href="format.sty" type="NaviStyle//1.1">
<link rel=style href="format.dsssll" type="DSSSL-Lite//1.0">
<title>A Styled Document</title>
Reasons for this extension:
* Some servers still cut off file-extensions at three
characters, making it very difficult to reserve distinct
extensions for every possible notation and conformance level.
* Different vendors may try to use the same extension to identify
their style notations. (How many other vendors besides NaviSoft do
you think are going to want to use '.sty'?)
* Sending out HTTP requests to get the content-type of every sheet
listed could cause a noticable delay in loading a document.
* Even with the current set of content-types, misconfigured
servers are a frequent problem. A succession of many new
content-types for style-sheets could exacerbate this problem.
(This is to say nothing about documents which are being served by
protocols which do not pass the content-type at all.)
There should also be some way of associating a style sheet with certain
display properties or platforms, although it is not clear to me how
this could be gone about.
