Hi there,

here are some comments on the HTML Techniques document:

1.1 The !doctype statement:
* DOCTYPE should be upper-case, as per XML specification, though 
lower-case is allowed in HTML
* Example: The example does not show an English-language document 
because there is no lang-Attribute. The 'EN' in the formal public 
identifier does _not_ specify the document's language.

1.2 The title element
* Sentence "All documents, ...": It's not the frames (frame elements) in 
a frameset that should have a title element, but the document loaded in 
these frames.

5.1 Emphasis
* According to <http://www.w3.org/TR/html4/index/elements.html>, the b 
and i elements are not deprecated in HTML 4.01. XHTML 1.0 also does not 
deprecate them.

5.2 Abbreviations
* "This also applies to shortened phrases used as headings for table row 
or columns. If a heading is already abbreviated provide the expansion in 
abbr." This may leed people to think that they should put the expansion 
of an abbreviated table header into the abbr attribute. The HTML 
specification defines a different purpose of the abbr attribute. 
Although the example is ok the sentence should be clearer.

6.1 Ordered lists
* I think the long numbering format (1.2.1) could be a UA issue. E.g. a 
screen reader could provide this funcionality though the browser it uses 
only shows the short format.

8.2 Table structure in layout tables
* Sentence "Do not use ...": In HTML, the tbody element is an at least 
implicit child of the table element. So it is part of the DOM.

9.8 Hide link groups
* No need to explicitly mention IE. The link URL appears in the status 
bar of many desktop browsers.

9.9 Keyboard access
* Although there is much trouble with the use of letters as access keys, 
letters are used in the examples.

12.7 Alternative content for embed
* There is no information about embed being invalid HTML or XHTML (like 
for marquee or blink).
