Missing Text in Nested Lists

Hi,

I have been using DocBook XSL stylesheets in conjunction with AsciiDoc to create html files.  AsciiDoc might produce something like the attached XML file (error.xml), which contains a nested list.  However, when I apply stylesheets to it, some text disappears as indicated below.

1. List Item #1.
2. List Item #2. <-- THIS ITEM DISAPPEARS
   a. Nested List Item #1.
   b. Nested List Item #2.
   c. Nested List Item #3.
3. List Item #3.

I have been using the following command:
>> xsltproc -o error.html DOCBOOK_DIR/xhtml/docbook.xsl error.xml
where DOCBOOK_DIR is the DocBook installation directory for docbook-xsl-1.75.0.

Can someone explain what's wrong?
