Nothing wrong with that formulation—I guess I have enough XSLT 2 brain damage
that I forget about being able to select the head of a possibly multi-item
sequence as a shortcut for the if/then/else I wrote 😊
I spend a lot of time (or have spent) correcting older XSLT code to use exactly
that formulation so I should really start there …
Cheers,
E.

The typical way to do it is to have the processing of the section element get
the value from the preceding target element:
<xsl:template match="section">
<xsl:variable name="id" as="xs:string?"
select="preceding-sibling::target[1]/@refid"
/>
<xsl:copy>
<xsl:attribute name="id"
select="if ($id) then $id else generate-id(.)"
/>
<xsl:apply-templates mode="#current"/>
</xsl:copy>
</xsl:template>
What's wrong with
<xsl:template match="section">
<xsl:copy>
<xsl:apply-templates select="@*" mode="#current" />
<xsl:attribute name="id"
select="(preceding-sibling::*[1][self::target]/@refid,generate-id(.))
=> head()" />
<xsl:apply-templates mode="#current" />
</xsl:copy>
</xsl:template>
I am assuming XSLT 3, here, but that should be a fairly safe assumption
these days.
