Hi Jose,

Thanks for the explanations! (esp. very good to know that an XML id attribute has to start with a letter, "_" or ":") 
It actually works fine now.

Hello Jean-Luc,

It was easier to understand the problem this way.

This is a double bug. It's a bug in your xml document because an XML id attribute has to start with a letter, "_" or ":" , not with a 
digit (see the XML spec). If you change the ids to be conformant, then 
it'll work.

It's a bug in Amaya because it detects that your XML file is wrong, but doesn't stop and give you a warning, it just continues and generates the annotation.

I think this is related to 1. too because I can't reproduce it.

I think that using IDs is the best solution if you want to have fine-grained annotations of documents whose structure may change with time. This way you won't
loose them. There's a special Amaya function to help generate ID values:

	Links / Add/Remove IDs

It may be useful or not to you, depending on your context.

Hope this helps,
