> Unicode character U+FF0B: Fullwidth Plus Sign not allowed in attribute value with XML 1.0 version.
> This XML fragment is reported by Xerces as invalid:
> {code}<?xml version="1.0"?>
> <abc xmlns:＋="https://iso20022.plus"></abc>{code}
> {quote}Element or attribute do not match QName production: QName::=(NCName':')?NCName.{quote}
> Although FF0B seems to fit in this range of allowed chars [#xE000-#xFFFD] for XML 1.0:
> https://www.w3.org/TR/REC-xml/#NT-Char
> If I change the XML version to 1.1 the validation starts working again.
