[news.eclipse.modeling.m2m] [ATL]Does ATL Engineer always transfer "Elem

[xxcs214@xxxxxxx (Shan)]

When I transform an example:

	source model:

	<book xmlns="http://www.m2matl.com/book"; name="ass" code="asss"> 

target model which I supposed should be :

	<prdocut xmlns="http://www.m2matl.com/prdocut";>
	    <name>ass</name>
		<code>asss</name>
	</product>
	
	is :

	<prdocut:Prdocut xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"; 	 
xmlns:prdocut="http://www.m2matl.com/prdocut"; code="asss" name="ass"/>

Target model'style is same as book that "name" and "code" are both 
attributes.


my atl source:
-------------------
module B2P; 
create OUT : Product from IN : Book;
rule Book2Product {
   from    
     b : Book!Book    
   to   
     out : Product!Product (    
   	   name <- b.name,   
      	   code <- b.code   
     )
}
-------------------

Is my alt rule right or wrong? 
If it is wrong, how to defiine atl rule to make sure get correct result? 
else does atl engineer always transfer "Element" to "Attribute" when the 
element is simpleType?
