In the "Address Syntax" section, 1st page, it says that SID addressing is used in target and ref attributes (and anything else that references an SID). However, some things are inconsistent with that definition.
The following are of type xs:token and the spec says that they point to an ID.
* <setparam ref=xxx>
* <param ref=xxx> in kinematics and render targets
* <connect_param ref=xxx> (actually, spec doesn't say whether it's SID or ID and it should)
So--do these refs really point to IDs or to SIDs? If the former, then the address syntax section is incorrect?
*<import ref=xxx > (spec & schema say it references an SID, but defined as xs:token)
