In package-100 I'm getting two empty <row> elements at the start, as in the expected results:

In package-101 I'm getting one empty <row> element, which isn't expected.

The first empty row appears to arise because we're applying templates to the variable $csv:quote-ok, and the value of this variable is not an empty sequence, but a document node with no children (because the xsl:variable has no "as" attribute).

I can fix the results for package-101 by adding 'as="xs:error?"' to the xsl:variable declaration, but when I do this, package-101 only has a single empty <row/> at the start: which is, I think, the correct result.
