For my knowledge, that is incorrect.  Latin1 isn't a subset of UTF-8, for
the contrary, the opposite is true:  UTF-8 is a subset of Latin1.  If you
want to generate a XML document (result tree) that has *support* for Latin1
characters, like: á,é,í,ü,ë, etc. you have to generated the XML declaration
with Latin1 encoding (ISO-8859-1), otherwise the result would not be well
formed XML, just like David said:
