Not support

(At least not at this time)

There are a couple of technical issues:

1) I do not see any explanation of - or examples for - the use case where LSP attributes would apply to a 
hop in an LSP and not to the entire LSP.  If attributes apply to an entire LSP, than there are existing ways
to do this. If it is possible to have an attribute that applies to a single hop in the LSP, does this not raise
issues with "weak-links"?

2) I strongly suspect that this approach MUST rely on information present at the signaling initiator that 
would be "too much information" about nodes and links in the LSP-path.  This information may change,
even between the time that the path is determined (by whatever means) and the time that signaling is
initiated.
