First, the reason you can't file this DP is because it has no assigned headings to take you to the enroute structure. You've got some pre-published standard initial turn after takeoff but no where to go after that. To summarize, the DP has you fly a heading (or group) up to 13, 15, or2400' (based most likely for the anticipated routing of other traffic) after which vectors take over.
Like every other DP, it's shorthand to make taking it down and reviewing it more easy (a picture paints a 1000 words). And like any other clearance, short-had or long winded, it's subject to be overridden by more current and specific ATC instructions.
