Al,

Reading more of the news item I come to the following:

The following SQL code will construct a table called Customer with each 
record containing a custid, an integer, and an optional name, a string. 

CREATE TABLE Customer
   ( name string NULL,
     custid int); 

In Xen, this table could be created with the following line of code: 

sequence{ string? name; int custid; }* Customer; 

I wonder why they didn't adopt the SQL syntaxis, which is already a standard and easier to read, to boot?
