Submission is bouncing back

Hi Team,

There is an urgent filing for MELLIZYME BIOTECHNOLOGY LIMITED (Company number 11824812) where the submission is bouncing back, we have validated the submission on our end and the IXBRL holds up.

The error we are getting is Entity: line 9: parser error : XML declaration allowed only at the start of the document.

We’d be grateful if you could provide any assistance as the filing deadline is 31 December 2021.

With kind regards,



I think you probably need the XML forum -

Good luck
