AFAIK cslatex has never been officially released for xetex and luatex.
Several years ago cslatex was declared obsolete and unmaintained.
However, the old documents cannot be easily compiled with nowaday's
latex. In addition, CSTeX, which is currenlty mostly csplain, contains
Czech and Slovak hyphenation patterns that are used in all engines and
all formats. Use of cslatex for new documents is discouraged but
csplain is still actively maintained by Petr Olšák and used by many
users with all engines.
