A useful enhancement would be the ability to
highlight attribute names and values in different
colors, different from the element start tag. This
will really help in cases where there are a large
number of attributes. I understand, per Lennart
Staflin's reply to my posting "help: attribute
highlight" on the "Open Discussion" forum, that
this feature is not currently available.
Maybe it is possible to provide a MARKUP-TYPE
of 'attribute-name' and 'attribute-value' or
something like that, for sgml-markup-faces.
