Hi Chris,

That is because DTDs and validators are a quick and easy way to make these 
checks. If you know other ways, please let me know. I now realise I forgot 
to check if Tidy and JTidy can be used here.

As Gregg has pointed out, we may have to fix the title.
However, I don't understand why you think that the title implies that a DTD 
is necessary. "Necessary" in what sense?
- For this technique, it is necessary to have a DTD or other documentation 
that specifies which attributes have ID values, but since this is a 
technique for HTML, this is not a problem.
- For this technique, it is not necessary to specify a document type 
declaration, but it helps.
- For this technique, it is not necessary to validate against a DTD, but it 
is a quick and easy way to see if you satisfy the technique. However, 
validation is clearly a stricter requirement. So, in a validation report, 
you would look only for errors related to ID values and the use of opening 
and closing tags.

I suppose you mean H75. H74 is the non-XML counterpart of H75; we split 
this up because HTML - being based on SGML - does not know the concept of
