ixbrl tagging for free share schemes

Last year I tagged share option schemes using the share option tags under notes to accounts and used the LTIP tags under Directors Report Directors Remuneration section for tagging a free share scheme as it mainly applied to Directors and senior staff.  This year I have a free share scheme that is open to all employees.  It seems wrong to tag using LTIP tags from Directors Report as you have to give a dimension of "All entity officers".  However, the share option tags don't apply either.  Do I leave the notes untagged?  I'm using Iris Openixbrl for tagging and this will affect about 20 companies that I have to tag.
