New in XSLT 3.0. Allows a node other than the context node to be copied. This is useful when the instruction appears inside xsl:function. |

Used only when copying element nodes. Attributes of a generated element can be defined by reference to named attribute sets, provided as a whitespace-separated list. They are applied in the order given: if the same attribute is generated more than once, the later value always takes precedence. |

Notes on the Saxon implementation
Modivated by streaming, the on-empty attribute was introduced in an
early Working Draft for XSLT 3.0, but later removed and replaced by the new xsl:on-empty, xsl:on-non-empty and xsl:where-populated
instructions. The on-empty attribute was implemented in Saxon 9.5,
but removed in 9.7.
Details
When xsl:copy is applied to an element node, the start and end
element tags are copied; the attributes, character content and child elements
are copied only if xsl:apply-templates is used within xsl:copy.
Examples
A template that copies the input element to the output, together with all its child elements, character content, and attributes:
<xsl:template match="*|text()|@*"> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:apply-templates/> </xsl:copy> </xsl:template>
