[DFDL-WG] clarification: textBooleanTrue/FalseRep cannot be empty string? textStandardNaNRep and friends cannot be empty string.

[Steve Hanson]

Agree that textBooleanxxxRep properties should state empty string not 
allowed.

The textStandardNanRep and textStandardInfinityRep properties should state 
empty string not allowed. The others you list already mention empty 
string.

We don't stipulate that textBooleanTrueRep nor textBooleanFalseRep cannot 
be empty string.

We do stipulate that entity ES is not allowed. So I expect these 
properties cannot be "" meaning the same thing that "%ES;" would mean. 
Since we disallow the latter, we should disallow just "".

Similarly, for textStandardGroupingSeparator, textStandardExponentRep, 
textStandardNaNRep, and textStandardInfinityRep we specify that the string 
literal value behaves as specified in textStandardDecimalSeparator, but we 
don't specify that these cannot be empty string (which is specified in 
textStandardDecimalSeparator, but not in the "Text Number Character 
Restrictions" part of that property description that is referenced from 
these other properties.)

ES and WSP* are not allowed, so almost certainly empty string should not 
be allowed.
