Unqualified element in XSD definition

For some reason, we may need to define elements in XSD to be
"unqualified".

According to the design patterns of XSD, it seems they do not recommend
to define elements in this way....it seems it will influence XPATH /
XSLT, etc...

Anyone has any experience on this? Any problem will be caused by
unqualified elements?

Thanks a lot for your advices!
