    <thetext>In §3.5.3.5, immediately after the definition of error XTSE3080, we have the Note:

This means that abstract components must either be overridden in a using package by a component that supplies a real implementation, or they must be accepted with visibility=&quot;hidden&quot; (see 3.5.3.2 Accepting Components), which has the effect that any invocation of the component raises a dynamic error.

I don&apos;t believe this note is correct. 3.5.3.2 says that if an abstract component is not matched by any xsl:override or xsl:accept declaration, then the corresponding component in the using package has visibility=&quot;hidden&quot;, which is exactly as if it were explicitly accepted with hidden visibility.

(One could argue that the Note is correct if &quot;accepted&quot; is read as &quot;explicitly or implicitly accepted&quot;, but that&apos;s not the natural reading.)

I think that XTSE3080 can now arise only if the top-level package explicitly declares an abstract component.</thetext>
