Two examples of how Selection and Connection Properties may be used to sort branches are provided below: </ins> <del> Interface Type: If the application specifies an interface type to be preferred or avoided, implementations should rank paths accordingly.  If the application specifies an interface type to be required or prohibited, we expect an implementation to not include the non-conforming paths into the three. </del> <ins> "Interface Instance or Type": If the application specifies an interface type to be preferred or avoided, implementations should rank paths accordingly.

If Protocol or Path Selection Properties contain any prohibited properties, the implementation should first purge branches containing nodes with these properties. For required properties, it should only keep branches that satisfy these requirements.  Finally, it should order branches according to </del> <ins> Prohibit, Require, Prefer, Avoid.  If Selection Properties contain any prohibited properties, the implementation should first purge branches containing nodes with these properties.  For required properties, it should only keep branches that satisfy these requirements.  Finally, it should order branches according to </ins> preferred properties, and finally use avoided properties as a tiebreaker. <del> For Require and Avoid, Path Selection Properties take precedence over Protocol Selection Properties.  For example, if the application has indicated both a preference for WiFi over LTE and for a feature only available in SCTP, branches will be first sorted accord to the Path Selection Property, with WiFi at the top.  Then, branches with SCTP will be sorted to the top within their subtree according to the Protocol Selection Property.  However, if the implementation has cached the information that SCTP is not available on the path over WiFi, there is no SCTP node in the WiFi subtree.  Here, the path over WiFi will be tried first, and, if connection establishment succeeds, TCP will be used.  So the Path Selection Property of preferring WiFi takes precedence over the Protocol Selection Property of preferring SCTP. </del> 4.4.

text: Connection properties really are about configuring something, but I still say that being able to use them as early input is good. I agree that the implementation isn't super clear as they don't come with a require/prefer/... etc. qualifier, but then we just offer some freedom to implementers.
NAME I just pushed a commit that updates the selection and connection properties text, removing "connection" almost everywhere, but adding a disclaimer in the beginning that says that connection properties should be configured as early as possible because they can influence decisions made by the implementation, and "In the remainder of this document, we only refer to Selection Properties because they are the more typical case." Frankly I'm not sure this is better... but it does remove most of the "selection and connection" double mentions that you pointed out.
Fixed up branch building and resolved merge conflicts. I'll merge this in later today before the posting deadline.
Cool thanks! Sorry if I messed something up

Thank you for updating this – looks good! just needs s/send-params/msg-properties/ and merging
