The document makes use of Seq and Bag for Complex attributes[1]. The
problem is that, from an RDF/RDFS point of view, both of these are quite
ill-defined semantically. Though formally they are not deprecated in the
latest (2004) version of RDF, this was more due to chartering and
administrative reasons rather than anything else. From a Semantic Web
perspective it would be better if a new W3C recommendation could avoid
using those.

For Bag-s, multivalued properties could be a clear alternative; lists
(collections) are a clean alternative for Seq-s.

While one of the major rationale behind the development of the CC/PP 2.0 specification is to integrate the latest version of RDF, it is not its only goal. In order to ensure a coherent framework and full compatibilities with OMA UAProf 2.0 specification ([1]), it is essential to have both spec. based on the same RDF version. So, given that BAG and SEQ are not currently deprecated, the WG is proposing to keep their usage in this version of the specification in order to restore the compatibility between CC/PP 2.0 and UAProf 2.0. Then, due to ongoing enhanced cooperation between OMA and W3C particularly in the Mobile Web Initiative, we can imagine that both spec in the future could evolve together to take into account the latest development of RDF.
