Historically, the dumpxml command reject any unknown arguments, for instance:
virsh dumpxml fedora xxx
However, after v8.5.0-rc1~31 the second argument ('xxx') is treated as an XPath, but it's not that clearly visible. Therefore, require the --xpath switch, like this:
virsh dumpxml fedora --xpath xxx
Yes, this breaks already released virsh, but I think we can argue that the pool of users of this particular function is very small. The sooner we do this change, the better.

Opps, shouldn't we do the same change for all the other 'xpath' parameters.
I guess we should. But I worry that we might break some users scripts. But I guess if you're okay with it then so am I. Michal
