Some comment about the production UnaryExpr

To whom it may concern,

 

Hello,

 

My name is Kwang-Young Kim(kykim@hit.co.kr). 

I am working for Hyundai Information Technology, Co., Ltd.

 

I have some comment about the XPath versoin 1.0 specification.

 

I think that the production rule for UnaryExpr in XPath should be 

the following :

 

   [27] UnaryExpr ::= UnionExpr 

                      | '-' PrimaryExpr

 

instead of :

  

   [27] UnaryExpr ::= UnionExpr

                      | '-' UnaryExpr

 

I am looking forward to hearing your response.

And I thank you a lot for spending your valuable time in reviewing 

my writing in advance.
