Hi Folks,

I created a sequence (1, 2, 3) as follows:

<xsl:variable name="list" select="(1, 2, 3)" as="xs:integer*" />

I checked that $list contains 3 integers:

<xsl:message>count($list) = <xsl:value-of

Sure enough, the output shows that there are 3 items:

count($list) = 3

Next, I want to store that sequence of integers in an element, along with

<xsl:variable name="document" as="element(Document)">
     <Document>
         <Greeting>My List</Greeting>
         <List><xsl:sequence select="$list" /></List>
         <Ending>The End</Ending>
     </Document>
</xsl:variable>

Does the <List> element contain a sequence of 3 integers:

<xsl:message>count($document/List) = <xsl:value-of

Yikes! No it doesn't:

count($document/List) = 1

How to do what I want to do? That is, how to store the sequence of integers

in an element, along with other elements, such that I can pull the sequence
out of the element and immediately operate on the sequence? If that can't be
done, then what's the right way to do what I want to do?

That expression will always return the number of "List" elements. If you
use a schema and give that element a list datatype then I think that
with schema-aware processing
  $document/List/data()
would give you a list and you could of course count that list with e.g.
  count($document/List/data())

    <xsl:import-schema>
        <xs:schema>
            <xs:element name="List" type="int-list"/>
            <xs:simpleType name="int-list">
                <xs:list itemType="xs:integer"/>
            </xs:simpleType>
        </xs:schema>
    </xsl:import-schema>

    <xsl:template match="/" name="xsl:initial-template">
        <xsl:variable name="list" select="(1, 2, 3)" as="xs:integer*" />
        <xsl:message>count($list) = <xsl:value-of
select="count($list)"/></xsl:message>
        <xsl:variable name="list-element" as="schema-element(List)">
            <List xsl:validation="strict">
              <xsl:sequence select="$list"/>
            </List>
        </xsl:variable>
        <xsl:message>count($list-element) = <xsl:value-of
select="count($list-element)"/></xsl:message>
        <xsl:message>count($list-element/data()) = <xsl:value-of
select="count($list-element/data())"/></xsl:message>
        <xsl:message select="$list-element instance of
schema-element(List)"/>
    </xsl:template>

you would need to write a more complex schema for the more complex
sample you had I think, I am not sure whether you could use a schema
type for that element inside other untyped elements.
