case-sensitivity of the names of spreadsheet tables

Hi,

It seems that most (all?) spreadsheet implementations supporting ODF
restrict the names of the various tables (sheets) in a spreadsheet
document to be distinct under case-insensitive comparison, ie. you can
not have 2 sheets (tables) called "Sheet1" and "sheet1".

I can't find any statement in ODF1.2 that requires that. Is there such a
statement?
