Below are the syntax rules for Name (copied from the W3C XML
specification):

Names and Tokens
[4]    NameChar    ::=    Letter | Digit | '.' | '-' | '_' | ':' |
CombiningChar | Extender 
[5]    Name    ::=    (Letter | '_' | ':') (NameChar)* 
[6]    Names    ::=    Name (S Name)* 
[7]    Nmtoken    ::=    (NameChar)+ 
[8]    Nmtokens    ::=    Nmtoken (S Nmtoken)* 


As you can clearly see, a name cannot start with a digit.

Therefore, it is not possible for any well-formed XML document to
contain an element or an attribute or a namespace ' named "0"  '
