No CMSIS DAP Jtag on board, that would require a second processor to act as the CMSIS DAP jtag. The JTAG socket, which is connected the SWD port of the LPC, allows you to connect your own CMSIS-DAP (or any other) SWD debugger.
I think that's enough acronyms
LPC Link 2 is a a cheap SWD Debugger, mbed have released source code for their M0 they use as a CMSIS DAP debugger it maybe possible to use this with a second DipCortex M0/M3 to create your own debugger.
