Cross-references to sense numbers
If cross-reference content refers to a sense number within another entry, the target destination of the cross-reference should still be the id attribute value of the destination entry.
The number of the sense should be identified using a span tag with role="senseNum".
Example
<xrefGrp>See <xref ref="acref-9780195123456-e-0075" type="2">space <span role="senseNum">2</span>
</xref>
</xrefGrp>
This should not be confused with homograph numbering.
