Hi,
This is a leftover 'feature' from V1 of Php.XPath. V1 used to ignor the
header, so the idea was to replace it by <?xml version="1.0"?> by default
when exporting to a file. Then in V2 the user had the option to overwrite
it and in V3 we're able to keep the header 'as is' but exportToFile() would
still overwite it by default. 
We could change the behaver but it could break ppls code.
