Hi,

having a use case and requirements document is very important, not only for
the standardization group but also for the industry and the
research/academia. The document is setting the base requirements for the
different verticals and creating a knowledge base that can be used in the
future by researcher and developer companies to improve or create new
technologies targeting a particular use case.

Not sure why there is discussion about the suitability of this document.
Can someone clarify?

regards
Xavi
