Case sensitivity

As XML is a case-sensitive language, a Scheme with case-sensitive reader is HIGHLY RECOMMENDED for SSAX/SXML applications.

The following Schemes provide case-sensitive readers:

Bigloo	Default, since version 2.4a
Chez Scheme	(case-sensitive #t)
Chicken	Default, since version 1.21
DrScheme	Check option: Language -> Choose Language -> Show Details -> Case Sensitive See also PLT Schemes
Elk	Command line option -g
Gambit	Default
Gauche	Default, since version 0.5
Guile	Default
JScheme	Default
Kawa	Default
Ksi	(set-ksi-option! '*read-case-sensitive* #t)
ksm	Default
MrEd	See PLT Schemes
MzScheme	See PLT Schemes
PLT Schemes	Command line option -g or --case-sens or #cs prefix in source code or (read-case-sensitive #t) See also DrScheme
PS3I	Default
rscheme	Default
SCSH	Default
SISC	(case-sensitive #t) makes the reader case sensitive

R5RS
string->symbol function produces case-sensitive symbol on R*RS compliant Schemes

So, any R*RS compatible Scheme may be used with SSAX/SXML even without case-sensitive reader. Yet
'(foo (bar) (baz))
is better than
`(,(string->symbol "foo") (,(string->symbol "bar")) (,(string->symbol "baz")))
isn't it?
