Re: [xml-dev] complexTypes and attributes

[Umut Emin <j.s.bach@o2online.de>]

Hei Fraser,

thank you for the answer. Ok, then i have to put the attributes outside
of the <xs:sequence>. Must it be always after sequence tag, could i
place the attributes before <xs:sequence> too. To me, it is easier to
read the xml if i have them before.
