Dear Sir/ Madam

I am looking to file the accounts in IXBRL format and the error message is "the 2016 IE FRS 102 taxonomy". I emailed this query with the Revenue and they responded saying that we will need to declare and tag the submission with FRS 102 taxonomy that is accepted by Revenue. Can someone please indicate how we fix this issue so that the IXBRL file is acceptable by the Revenue. One thing I noticed is that the IXBRL file generated by Sage is HTML and the Revenue clearly stated that the file should be in XHTML and not in HTML. Any thought on this. 

Let me know.

Regards,

Rehan
