I agree. And putting the height & width in the style sheet will
immediately break validation from the W3C validator. Most of the other
items make sense, to some point, but for other reasons.

I think if you code to XHTML 1.0 Transitional or higher, you're doing
good. Add your accessibility and other needs after that, and you'll end
up with a very stable site that should work in most modern browsers.

Subject: RE: [WebAIM] ISO-HTML

Well, I guess I will not be writing "ISO-HTML" any time in the near
future. IMHO, image height and width belong in the HTML not in the
stylesheet otherwise you need an ID for every image and a stylesheet
that is either very bloated OR can only be applied on a page by page
basis. For that same reason No. 6 is is a bit silly. They will defer to
the W3C for CSS without making it a "standard' but will not accept HTML
from the W3C.

I will continue to use the W3C XHTML doctypes.

The ISO -- International Organization for Standardization -- consists of
the national standards institutes of 151 countries, on the basis of one
member per country, with a Central Secretariat in Geneva, Switzerland.
It promulgates, develops and maintains world wide technical standards.

Note that the W3C (World Wide Web Consortium) only makes recommendations
-- it is the ISO that publishes standards.

The International standard for HTML is prescribed by the Document
https://www.cs.tcd.ie/15445/15445.html and the Users Guide for ISO/IEC
15445:2000 (ISO-HTML) is at https://www.cs.tcd.ie/15445/UG.HTML

Features of ISO-HTML .....

1. The hierarchy of the header elements (H1, H2, H3, H4, H5 H6) is
rigidly enforced. For example, H2 is not allowed to precede H1 at any
place in a document.

2. HEIGHT and WIDTH parameters for IMG must be designated in style

3. Numerous W3C HTML 4.01 elements are refined in ISO-HTML.

4. Numerous W3C HTML 4.01 attributes are omitted from the standard or
their use is restricted as outlined in the following quote from the
Users Guide ..... "The W3C Recommendation for HTML 4.01 provides a
number of attributes that are not supported by the International
Standard. They have been omitted because they are used to describe
appearance rather than structure, or because the feature is considered
to be still too unstable or immature for an International Standard."

5. The Standard separates content from presentation as delineated in the
following quote from the Users Guide ....... "The International Standard
is based on the well established principle that it is good document
design to separate the content of a document from the intended style in
which it is to be presented to a reader ..... "

6. The methodology for accomplishing presentation is outlined in the
following quote from the Users Guide ..... "Although the International
Standard does not specify a style sheet language, this User's Guide
recommends that authors of ISO-HTML documents use Cascading Style Sheets
as specified by the World Wide Web Consortium."

7. Style sheets must be linked -- embedded style constructs are not
