[SDO-3]: Suggest: remove the {property '.' index_from_0} from sdo xpath syntax

["Hongbo,Yang" <yanghb@primeton.com>]

 

Hi all,

 

In SDO2.1 ,there is both

| property '.' index_from_0  

 and 

| property '[' index_from_1 ']'

in syntax of xpath.

 

It has two defects :  firstly,index_from_0 is not subset of xpath as described in SDO 2.1

                      secondly, '.' is not conveniently to combime with OGNL or web FrameWork.

 

So i suggest to remove the '.' index_from_0  from SDO in 3.0
