According to the March DTD [1] REV and REL are NAME attributes:
<!ENTITY % linkType "NAME"
rel %linkType #IMPLIED -- forward relationship type --
rev %linkType #IMPLIED -- reversed relationship type
So how they are treated with respect to case is determined by
the HTML SGML Declaration[2]. The SGML Declaration says:
NAMECASE GENERAL YES
which means that in the HTML DTD, upper case versions of letters are
converted to their lower case version before processing.

The TITLE attribute is CDATA. Case is preserved in CDATA attributes.
On a related note, there are lots of people on the Web with questions like
this that do not konw how to read a DTD. Is there an introductionry
text online?
