trying wrapping code within script cdata:

<script> //<![cdata[     ...code containing xml declaration (`<?xml version="1.0"?>`) //]]> </script> 

so xml declaration isn't interpreted part of enclosing document. xml declarations can appear @ top of xml document (and there can 1 of them @ most).

if doesn't resolve problem, examine you're outputting xml declaration. make sure there no visible or invisible content ahead of xml declaration, , make sure there not multiple xml declarations in output. more details see:

• are multiple xml declarations in document well-formed xml?
• the key causes , resolutions of error, the processing instruction target matching "\[xx\]\[mm\]\[ll\]" not allowed.
