xsltproc and whitespace with <indexterm>

Hi All,

I'm using xsltproc 2.7.6 and fop {0.95|1.0} on Ubuntu 10.04 (x64). I'm
producing PDFs using docbook.xsl located at
/usr/share/xml/docbook/stylesheet/docbook-xsl-ns/fo/docbook.xsl.

When I add index terms between elements such as <chapter> or <section>
and <para>, the whitespace is showing up in the finished document.
That is, I will not see 'standard' spacing between a {chapter|section}
title and the first paragraph (which looks like it should be one
line). I will see double/triple spaced lines between the title and the
first paragraph. I also see similar between paragraphs.

I thought the whitespace between tags was extraneous and would be
silently discarded (for example, the whitespace caused by <indexterm>
below). Is this not the case?

Are there any work arounds to get back to standard line spacing?

      <primary>Term 2</primary>
    </indexterm>

    <para>...</para>

    <indexterm>
      <primary>Term 3</primary>
