Description Abel Braaksma 2018-05-03 19:00:33 UTC
The note at the bottom of 19.1.2 says:

> The string representations of numeric values are backwards compatible with 
> XPath 1.0 except for the special values positive and negative infinity, 
> negative zero and values outside the range 1.0e-6 to 1.0e+6. 
I assume what is meant here is actually:

* The range between 0 and +/- 1.0e-6
* The range between +1.0e6 and up
* The range between -1.0e6 and lower

I don't think the text will really puzzle readers, but I think it is not technically precise enough as it is written (unless what's written is correct, I don't know enough of the XPath 1.0 spec to be sure).
