Hi Rod,=0D=0A=0D=0AAs long as we have the same logic in "element" and "pr=
operty", we can disable either the value attribute either the body conten=
t depending on the way you prefer. I am agnostic on this.=0D=0AThe way to=
 define a value will be unique, but we will have in any case the possibil=
ity of defining directly on the property or in an "element". =0D=0AWe can=
 also define that when "element" are included in the property, it's neces=
sarly an array of collection with one item only?=0D=0AIn this case, all d=
efinitions are one way possible.=0D=0A=0D=0AJean-Pierre=0D=0A=0D=0A------=

is that there are 3 ways of defining =0D=0Aliterals:=0D=0A- in the body o=
f the property element (as before)=0D=0A- in a value attribute. I don't t=
hink this is a good idea, as =0D=0Aattributes can only hold simple string=

which is necessary anyway for a =0D=0Acollection.=0D=0A=0D=0AJuergen make=
s a good point about mixed collections of =0D=0Areferences and string dat=
a (which of course would be =0D=0Aconverted to objects). Initially I thou=
ght this was unlikely, =0D=0Abut I realised it has quite a few uses (with=
 the AOP proxy =0D=0Afactory, for example), and the <value> subelement I =
suggested =0D=0Ahandles it. (It's already implemented: see collections.xm=
l in =0D=0Abeanfactory.xml tests.)=0D=0A=0D=0AThe most consistent approac=
