I want to use the title of the current html chunk in a template.
if I wanted to use the id, I would have written <input value="{@id}"/>.
I tried
<input><xsl:attribute name="value">
~         <xsl:apply-templates select="node()"
~                              mode="object.title.markup.textonly"/>
~ </xsl:attribute></input>

but got nothing useful plus a ton of errors like

No template for "/book/part/chapter/section/subtitle" (or any of its
leaves) exists in the context named "title" in the "en" localization.

so: where is the title?

thanks!
