Template:Interlingua recommendation

Recommended practice:
 * 1) Avoid re-use of messages. Just because a message happens to have the preposition or term you want does not mean that is is the same sense as what it was defined for, or can grammatically be applied in the same way for your context.  Safer to simply define a new message.
 * 2) Templates should add the property  *Uses string: Uses strings: . This allows translators to see the context where the term is used.
