Definitions of Conjunction and Disjunction

Benjamin,
It may well be that my definitions are too narrow. I took as my inspiration the concepts of conjunction and disjunction as defined in logic, with the idea, as Mick mentions in another message, that Joint is too weak. But as you suggest, there are nuclei to which the notion of truth value is inapplicable.
I am open to suggestions!

Andy,
I'm not sure that truth would be an appropriate part of the definition. What if multiple clauses were conjoined that had some kind of irrealis, subjunctive or future verb forms as the main verbs? Also what would the difference be between Joint and Conjunction?

Chris,
I have not seen definitions of these relations, but I have felt the need for them. I would be interested in what others think, but in the meantime I propose the following :
Relation Name
Conjunction
Constraints on Nucleus
Multi-nuclear
Constraints on Combination of Nuclei
Writer claims that all of the nuclei are true
The Effect
Reader recognizes that the writer claims that all of the nuclei are true
Locus of Effect
Multiple Nuclei
Example
He had the means, he had the motive, and he had the opportunity.
Relation Name
Disjunction
Constraints on Nucleus
Multi-nuclear
Constraints on Combination of Nuclei
Writer claims that at least one of the nuclei are true
The Effect
Reader recognizes that the writer claims at least one of the nuclei are true
Locus of Effect
Multiple Nuclei
Example
Either he was not at home, or he went to bed early.

Dear list members,
Recently, while using Mick O'Donnell's RST Tool, I noticed two multinuclear relations listed there which I did not find defined on the RST website or anywhere else. I would greatly appreciate it if someone could help me find the definitions (preferably with examples) of the Conjunction and Disjunction relations. Any citation for these would be very helpful. Thank you.
