Description Sandy Gao 2005-09-14 18:46:16 UTC
Part 2: Datatypes frequently defines the lexical representation of one type as 
a "truncation" of that of another, without ever defining what is meant by this 
term. Sometimes it seems to have the conventional meaning of omitting 
characters from one end of a string, as in: 

The lexical representation for gYear is the reduced (right truncated) lexical 
representation for dateTime: CCYY. [section 3.2.11.1] 
Other times the omitted characters are replaced by other characters, as in: 

The lexical representation for gDay is the left truncated lexical 
representation for date: ---DD . [section 3.2.13.1] 
It's not difficult to understand what is meant, but the document overall 
aspires to (and for the most part handily achieves) a higher standard of 
precision. For consistency, I'd like to see the term defined in 1.1.
