/ David Carlisle <davidc@n...> was heard to say:
| you might get away with it but if it's
| <Weight>0<!--I added this leading 0 for a reason-->123.4560</Weight>
| a query processor is allowed to report that as

Is allowed to, but doesn't have to. I hope, personally, to find and
use implementations of XPath2/XSLT and maybe even Query (if I ever
find a need for it) processors that keep the lexical forms around.

| <Weight>123.456</Weight>
| and information is lost.

Only if you applied a schema that said the data type of <Weight> was a
numeric. If you said it was a string, you'd get back just what you put
in.

And if that leading zero is important, I think I can argue that it's
not "just a number" to you (leading zeros aren't important in
numbers), so you'd be asking for trouble to type it as such in your
schema.

And if you want, you can validate it as a string in your schema then
cast it to a number when you want to do something numeric with it. You
don't have to let the data model builder munge it for you.

                                        Be seeing you,
