There are a couple of setup test cases which are publishing query only and they are marked with "//nohthor" and "//nothor" tags. In current implementation the Regression test engine doesn't handle those tags and publish all queries with all engines. This is not necessary based on the queries are called via SOAP call and that mechanism is not related to the current engine. 

However, there will be one setback with handling "//no<engine>" tag(s) in setup. The setup suite should be executed on all engines (or at least on Thor - to create multipart files, and on Roxie - to create single part files and publish queries) even if the regression target engine is only one or neither of them, otherwise some Regression Suite test cases (e.g. httpcall_*.ecl, soapcall.ecl)  will fail based on the missing published query.
