XBRL implementation is gathering pace (see my blog XBRL - more than just a regulatory tool ? ) and alongside I am starting to hear concerns with the way things are progressing.  There are worries about the impact of XBRL on internal management accounting and also concerns linked with the proposed switch to IFRS for SMEs in the UK.  On a positive note, the European Federation of Accountants (FEE) has produced a useful project update on XBRL which is well worth a read.
