Sorry for the incorrect (DTD) "flavors" nomenclature in my preceding post.
For HTML 4.0/4.01 they are "loose" "transitional" "strict" and "frameset"
For XHTML 1.0 they are "transitional" "strict" and "frameset"
The following implementations .....
ISO-HTML
XHTML Basic
XHTML 1.1
..... do not have any "flavors"
