Hi Jukka,

could you provide the file or the source file used to generate it ? In theory, 
the driver should be able to process any valid file. The checks are meant to 
detect things like <veeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeery_loooooooong_tag_name> 
that could result in denial of service, but there must be something wrong. And 
you don't get that with GML where there are similar checks ?
