Re: SPARQL variable names syntax: Second trial

Dear all,

Since there have been no reaction at all on my first e-mail, I would like to
ask you once a gain and especially of course ***the WG members responsible
for specifying the Grammar of SPARQL***. 
***
Why are you not to allowing the underscore "_" at the
Beginning of a variable name?
***
For details explanations and reason of my question please refer the previous
email.

Thanks in advance
Walid
