This verifies the "structural" restrictions on constructs encountered in a TASKGRAPH construct. There are also restrictions that apply to list items, specifically in the following contexts: - a list item on a clause on a replayable construct, - data-sharing attributes for a variable on a replayable construct. These restrictions are not verified, because that would require knowing which clauses (on a potential compound directive) apply to the task- generating construct of interest. This information is not available during semantic checks.
