[xsl] XSLT 3.0: Conflicting information about the possible parents of

Subject: [xsl] XSLT 3.0: Conflicting information about the possible parents of <xsl:context-item>

In the 2nd Last Call of the XSLT 3.0 specification, section "10.1.1
Declaring the Context Item for a Template"
defines an <xsl:context-item> in this way:

 "The xsl:context-item element is used as a child of xsl:template, to
declare the required type of the context item."

However, in Section "6.6.1Declaring modes"
(http://www.w3.org/TR/2014/WD-xslt-30-20141002/#declaring-modes)  (as
per my previous message), we find this text, referring to an
<xsl:mode> declaration:

"The above rules apply both to the attributes (other than name) of the
xsl:mode element itself, and to the attributes of the contained
xsl:context-item element if present."

So, this states that an <xsl:context-item> can be a child not only of
an <xsl:template>, but also of <xsl:mode>.

This evidence is further confirmed by the code example, contained in
section "2.9 Stylesheets and XML Schemas"

"Example: Asserting the Required Type of the Source Document

<xsl:mode typed="lax">
  <xsl:context-item use="required"

Based on these facts, I believe that the document needs to be
corrected to provide non-conflicting and unambiguous information about
all possible parents of <xsl:context-item> and its use as a child of
each of these parents.
