Look again at the grammar for XML:
http://www.w3.org/TR/REC-xml/#NT-prolog
[22] prolog ::= XMLDecl? Misc* (doctypedecl Misc*)?
[23] XMLDecl ::= '<?xml' VersionInfo EncodingDecl? SDDecl? S? '?>'
[24] VersionInfo ::= S 'version' Eq ("'" VersionNum "'" | '"' VersionNum '"')
[25] Eq ::= S? '=' S?
[26] VersionNum ::= '1.' [0-9]+
[27] Misc ::= Comment | PI | S
Notice in [22] that there can be zero or more Misc (in [27]), which can be one of a comment a processing instruction or a white space character.
So if there is no XML declaration present there may be zero or more white spaces before the start of the element.
Paul.
