n3 grammar : ambiguity for integer and decimal

Hi,

Looking for integer and decimal non terminal ( token ) definition on following n3 grammar specification:
  http://www.w3.org/2000/10/swap/grammar/n3-report.html

  and

  http://www.w3.org/2000/10/swap/grammar/n3.n3

The ebnf definition for integer and decimal are:

  integer : [-+]?[0-9]+

  decimal : [-+]?[0-9]+(\.[0-9])?

There is an ambiguity since "123" ( for example ) match integer and decimal

I propose 
  decimal : [-+]?[0-9]+\.[0-9]*

Width the above definition "123" match only integer, "123." match decimal. This look like C and Java standard for numéric constants

Best regards
