The Danish UNIX User Group (dkuug) has posted a complaint to the EU regarding the Danish approach to open standards. Read the complaint here: http://www.dkuug.dk/keld/complaint.pdf
The key issue is this:
The Danish state represented by ITST has made ECMA 376 mandatory from the 1st of January 2008 for cartain procurements in the Danish state, thus making the procurement unacceptably favouring a specific company and their product, and setting their competitors in the field of office software at a competitive disadvantage.
A key point is this report from Ovitas AS about openness and competition: http://www.itst.dk/arkitektur-og-standarder/Standardisering/Aabnestandarder/baggrundsrapporter/Research_OXML.ODF2.pdf/view
This complaint has raised the debate in the Danish media again, whether OOXML is an open standard or not.
