Which surprised me, because I wouldn't have expected 

<xsl:sequence select="document($paths)"/>

to work, then I went and looked at the spec for the surrounding
xsl:document, an instruction I don't think I've ever used.

Sequence constructor rules, item 4 -- 

http://www.w3.org/TR/xslt20/#constructing-complex-content

"Any document node within the result sequence is replaced by a sequence
containing each of its children, in document order."

So you just can't put a document node in a document node via any
sequence constructor, which makes sense.

So, yes, processor _has_ to be clever enough, it's in the spec. :)
