What is the reason behind these two concepts ??
Why do we have to think to which field must be promoted when we design the
schemas ?
Are these proporties stored in the context of the message ?

[ Post a follow-up to this message ]

Distinguished fields are only accessible in an orchestration.
This is tidier than using xpath() to access the message content inside an
orchestration

Promoted properties are put into the message context and available in the
pipelines and orchestrations.
If you wish to perform correlation, content based routing(subscription
filtering) or dynamic ports(setting pipeline and adapter parameters) then
you need promoted properties.
You can promote properties from a message schema(MessageDataPropertyBase) or
just declare message context properties(MessageContextPropertyBase) for use
in pipelines or adapters- (properties promoted from an envelope should use
MessageContextPropertyBase type as well)

Do you know where the documentation is for using xpath() method in an
expression? I can't find it in the BizTalk docs.

.. here is a good start to the xpath()

ok, but why is it the only way to do CBR ? I would also like to create
filters based on xpath expressions for example...
Because the drawback of promoted properties is that I must know which
elements I have to promote when I design my schemas...
