it was changed on-purpose. XHTML syntax is lowercase, basically this
lowers
the barrier when switching from SGML HTML to XHTML, and you have more
chances
of generating valid HTML in modern frameworks by using the lowercase version
than when using the uppercase version. The world is slowly moving toward
XHTML and this just reflects that tendancy :-)
