Since (at least some of major) existing user agents at the time HTML 4.0
was developed recognized fragment identifiers case-sensitively, that
option was unrealistic, unfortunately.

We do aware that this is weird, so XHTML 1.0 deprecated the 'name'
attribute, and XHTML Basic/1.1 removed the 'name' attribute, though,
ID is no longer case-insensitive in X(HT)ML.
