Hierarchical trust model is only one of many trust models.
Direct trust model is common where key exchange protocols are robust and
trusted. Peer-to-peer trust model (popularized by PGP)
is another model that is useful to develop a web of trust.
Note sure whether the term "trust model" in 006.9 means these kind of
models.
Need clarification.

Cheers,

The scope of "trust models" problem should include:

1) Management of trusted CA roots that may be embedded or
accessible in web services applications and client 
devices.
2) Exchange of authorization data, e.g., signed or 
trusted assertions.

W.r.t. #1, there is the X-TASS/XKMS specification:
	http://www.xmltrustcenter.org/research/docs/Xtass.pdf
	http://www.xmltrustcenter.org/xkms/docs/XKMS_1.1.pdf

W.r.t. #2, there is the OASIS SAML v. 1.0 specification 
and possibly posisbly the WS-Security spec:

I think this needs clarification.  I don't know what "a baseline for trust 
models" means.
