Conversion to Logical from Text

Hi,

Section "6.2.8 Conversion to Logical" says that

| Text, level 3 and higher applications examine the text; if the text
| matches the text "TRUE" ignoring case, then return TRUE, if the text
| matches the text "FALSE" ignoring case, then return FALSE, otherwise
| return Error. Note that case is ignored no matter what the value of
| “case-sensitive” is.  It is implementation-defined what happens if the
| text does not match “TRUE” or “FALSE” in a case-sensitive manner- it may
| return a logical value or an Error.

I think that's wrong and even worse than trying to interpret text as
numbers because it will definitely not work in different locales.
Instead, we should define that similar to "Conversion to Number", e.g.

Text: An application may return FALSE, an error value, or the results of
its attempt to convert the text value to a logical (and fall back to
FALSE or error if it fails to do so). Note that portable spreadsheet
files cannot depend on any particular conversion, and shall avoid
implicit conversions from text to logical.

Opinions?
