That massively simplifies things! Well we need to make sure people read CLA and know what it implies. Which unfortunately I can not tell you what it is since CLA at OASIS site is down: https://www.oasis-open.org/resources/open-repositories/cla/individual-cla I will reach out to OASIS to figure it out. > > If you like I can reach out to OASIS to confirm. > > Yes, that'd be very helpful, thank you. > > > -- > Manos Pitsidianakis > Emulation and Virtualization Engineer at Linaro Ltd
