Do you call out truss connections?

Assume you are talking about wood trusses? (please confirm)
For wood trusses the truss-to-truss connection is by the manufacturer whether truss, girder truss or other product.
For truss-to-wall or other non-truss structural member we design and detail the connection.
Here's a sample of some notes we've used in the past:
LATERAL FORCES APPLIED TO THE TRUSSES, SUCH AS DRAG TRUSS LOADS, COLLECTORS, ETC., ARE INDICATED ON THE PLANS WHERE APPLICABLE.
ALL TRUSS-TO-TRUSS CONNECTIONS ARE THE RESPONSIBILITY OF THE TRUSS ENGINEER.
DRAG LOADS (HORIZONTAL TRUSS TRANSFERS) CONNECTIONS BETWEEN THE TRUSS AND THE STRUCTURE ARE INDICATED ON THE PLANS WHERE APPLICABLE.
ALL TRUSS-TO-STRUCTURE (WALLS OR BEAMS) CONNECTIONS ARE INDICATED ON THE PLANS WHERE APPLICABLE.
IT IS THE RESPONSIBILITY OF THE TRUSS ENGINEER TO DEVELOP THE LOADING REQUIRED TO IMPLEMENT THE REQUIREMENTS OF SNOW PER NDS SPECIFICATIONS, APPENDIX A. THIS INCLUDES ADDITIONAL SNOW LOAD AT EAVES, AND UNBALANCED LOADING ON GABLE AND HIP ROOFS.
IT IS THE RESPONSIBILITY OF THE TRUSS ENGINEER TO REVIEW ALL OF THE INDICATED DESIGN SPECIFICATIONS, ROOF TRUSS SUPPORTS, AND DRAG DETAILS AND TO INCORPORATE THESE REQUIREMENTS INTO THE ENGINEERING DESIGN OF THE ROOF TRUSS SYSTEM.
THE TRUSS ENGINEER SHOULD DEVELOP A TRUSS LAYOUT PLAN FOR THE TRUSS SYSTEM THAT CLEARLY INDICATES THE TRUSS VERTICAL SUPPORT CONDITIONS, TRUSS-TO-TRUSS CONNECTIONS, DRAG TRUSSES AND COLLECTORS, AND ANY OTHER FIELD-INSTALLED REINFORCEMENT, INCLUDING FIELD-INSTALLED TOP CHORD REINFORCEMENT AT EAVES NECESSARY TO EXECUTE THE TRUSS SYSTEM DESIGN. THE TRUSS ROOF FRAMING PLAN SHALL BE SEALED BY A LICENSED PROFESSIONAL ENGINEER AND BE INCLUDED WITH THE INDIVIDUAL TRUSS CUT SHEETS. THE TRUSS ENGINEER SHOULD ALSO PROVIDE PROPER SUPERVISION OF ANY TRUSS COMPANY TECHNICIANS.
TRUSS BRACING: TEMPORARY ERECTION BRACING AND PERMANENT WEB BRACING SHALL BE DESIGNED BY THE TRUSS MANUFACTURER.
