            Bug ID: 29148
           Summary: [XSLT30] Text on constructing complex content says
                    that document nodes are removed, but this is not
                    always true
           Product: XPath / XQuery / XSLT
           Version: Last Call drafts
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSLT 3.0

  Target Milestone: ---

Under 5.8.1 Constructing Complex Content, we write (4th item):

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

However, when inside an xsl:variable, the result sequence implicitly contains a
document node. This document node is not removed. Conversely, if you write:

<xsl:variable>
    <xsl:document>+

you could say that the document not is not removed either, as the xsl:variable
will not have to be converted into a variable containing a document node.

Likewise, if you have as="document-node()", the sequence is required to create
a document node and it is not removed (if we did so, it would invalidate the
variable).

Though I am unsure how this could be written more clearly (rules elsewhere are
clear), I stumbled upon it, considering it an (albeit small) ambiguity.
