Sure ... but what is the problem?  There are a number of aspects of 
your XSLT and XSL-FO that should probably change based on what I 
read, but I can't tell which issue to focus on (but I can guess).

When you say you have a problem, what is happening that you do not 
want to happen?

You should probably be using start-indent= and end-indent= instead of 
padding because of the interaction with other blocks and the nature 
of the background colour (though it may not matter in this particular 
case, padding is not typically used for indentation).

Here you are counting note/note/para because your current node is 
note ... this is probably what your question is ... given that your 
current node is note, you should only be counting the para children: 
count(para).

You needn't use fo:character above, and the space between the 
character and the paragraph will be lost because it is in the 
stylesheet white-space ... and given you are dealing with paragraphs 
of information you are approaching this incorrectly.  You probably 
need to remove the block you had and replace it with something along 
the lines of:

  <xsl:for-each select="para">
    <fo:block start-indent="30pt" end-indent="30pt">
      <xsl:text>&#x25a1; </xsl:text>
      <xsl:apply-templates/>
    </fo:block>
  </xsl:for-each>

> </xsl:when>
>                                         <xsl:otherwise>
>                                                 <xsl:apply-templates/>

This now needs to be wrapped in <fo:block> after you remove it from 
after the note:

    <fo:block start-indent="30pt" end-indent="30pt">
      <xsl:apply-templates/>
    </fo:block>

But you really aren't clear which problem you are referring to, so 
hopefully one of the above will help.
