You put the attributes in a variable:

<xsl:variable name="new_atts">
    <xsl:sequence select="$orig_atts"/>
</xsl:variable>

By default, any untyped variable will be created as a document node.

You avoid that by using "as" to specify a type, specifically that this
variable is a sequence of one or more attributes:

<xsl:variable name="new_atts" as="attribute()+">
    <xsl:sequence select="$orig_atts"/>
</xsl:variable>

(Possibly zero or more, which would make it "attribute()*".
