[sv-bc] Re: [sv-ec] Is string valid data type for 'foreach' array

Hello,
According to  SV LRM 1800-2005
"Formal arguments of imported functions can be specified as open 
arrays." and nothing is mentioned about imported task for this context 
and Dhiraj raised a question on this.
and Doug answers Dhiraj that-
Formal arguments of imported tasks can not be  specified as open arrays.

And  you said that "a string can be considered a dynamic array of byte's"
So string datatype can not be allowd as a formal arguments of imported task.
 
But In SV LRM 1800-2005 sec 26.4.4  we found an example-
import "DPI" task checkResults(input string s, bit [511:0] packet);

So please make a comment on this.

Thanks,
 Moumita
