Hi,
I have routinely added anchors to pages using both name and id:
<a name="example" id="example"></a>
under the possibly mistaken assumption that at some stage "name" might
be deprecated but "id" was unlikely to be.
Can I ask what is accepted practice currently?
Thanks for your trouble,
Andrew

This is because the ID element type has a declared value of ID, while
the NAME element type has a declared value CDATA.
Values of attributes of declared value ID are case folded as specified
by the HTML SGML declaration which contains "NAMECASE GENERAL NO", but
CDATA values are never case folded.
But what about this?:
<http://www.w3.org/TR/html4/struct/global.html#adef-id>
id = name [CS]
i.e. ids are case-sensitive. Is it an error, or am I misinterpreting it?
For an extensive description of the issue, read: https://www.cs.tcd.ie/15445/UG.HTML#FOLDING

That name would be deprecated was announced with XHTML 1.0 and name
was deprecated for A and MAP in XHTML 1.1. Of course it is going to be in
HTML 4.x forever and XHTML is pretty much neither fish nor fowl so let's not
feed into that can of worms.
But not html 5... http://www.w3.org/html/wg/html5/diff/#absent-attributes
"name attribute on map, img, object, form, iframe, a (use id instead)."

Where is the DTD?

This is because the ID element type has a declared value of ID,
It does not. First, you mean "type", not "value",
André is right: it is called "declared value". This may be confusing,
because it is similar to the "type" in programming languages, but the SGML
spec uses "declared value".
and second, the type
of the id attribute is "name".
http://www.w3.org/TR/html4/struct/global.html#h-7.5.2
André refers to the HTML DTD. The HTML spec uses 'type' scheme on top of the
SGML rules, but a real SGML parser does not know about that.
>while the NAME element type has a declared value CDATA.
Values of attributes of declared value ID are case folded as specified by the HTML SGML declaration which contains "NAMECASE GENERAL NO", but CDATA values are never case folded.
Semantically, id="example" is strictly equivalent to id="EXAMPLE" and an HTML filter may apply such a case folding. However, name="example" isn't equivalent to name="EXAMPLE".
http://www.w3.org/TR/html4/types.html#h-6.1
This is untrue. Both attributes are marked "[CS]" (case sensitive), and
id="EXAMPLE" is not the same as id="example".
It is case sensitive on the 'HTML level', which is one step above SGML. A
SGML parser *does* fold id="example" into id="EXAMPLE" - HTML rules cannot
change that. HTML will then treat this uppercased string case sensitive.
