Remarks
DocWright never reads a file or fetches a URL to find a subreport. A ReportName comes from a
report definition, which is untrusted, so resolving it — against a catalogue, a folder the host chose, or a
fixed set of definitions — is the host's decision, made here.
The resolver is called once per subreport item per run, not once per row: a subreport in a tablix of a thousand rows asks for its definition once and runs a thousand times. It may be called concurrently when reports are processed concurrently, and should return the same definition for the same name.
