Hello, After what operation do you obtain that warning? Can you please provide more details ? <?xml version='1.0' encoding='UTF-8'?> is the XML declaration, you will find it at the beginning of almost every XML file. While this declaration is not absolutely necessary it is still useful because it specifies the encoding of the file. Regards, Adrian Buza Oxygen XML Editor support Gabrielle Burns wrote:

In Oxygen 11.2 and previous versions, the Results window lists this commonly repeated warning:

The HTML tag "?xml version="1.0" encoding="UTF-8"?" is not a valid HTML tag (it does not begin with an alphanumeric character).

Each of the DITA templates provided in Oxygen includes this standard notation at the top of the xml file:

<?xml version='1.0' encoding='UTF-8'?>

Is there some action you recommend to eliminate this error, such as removing this tag at the top of the xml files?

Thank you.
