Thank you, Susan. I have not thought of the group element. Though I do
not yet understand how exactly I should solve this first point. I do
not yet understand the standard in every detail. The way I see it,
"relevance" in the context of the group element refers to the
"relevant" attribute of a bind element in the model. Is that correct?
If so, I do not yet understand how I (as a user of my application)
could specify a bind element that would lead to the desired
effect. Could you give me a hint?

I guess, the simplest thing for my purpose would be something like the
following (with the example data in my last message). But as far as I
can see, this would be an extension.  Is that what you suggest?

    <xforms:repeat ref="/record-set/record">

      <xforms:group relevant="@type = 'author'">
	<h2>An Author</h2>
	<xforms:input ref="name">
	  <xforms:label>Author Name</xforms:label>

      <xforms:group relevant="@type = 'book'">
	<h2>A Book</h2>
	<xforms:input ref="title">
	  <xforms:label>Book Title</xforms:label>

Thank you. This "number" attribute is exactly what I was looking for.
