Re: [docbook-apps] trademark customisation

I'm afraid in XSL-FO there is no option to "test" for the current font-size 
and switch to an appropriate action.  That's because the XSLT step is 
separate from the XSL-FO step.  In XSLT, you can do xsl:choose to take 
different actions.  But the resolved font-size is not known until the 
XSL-FO step after all property inheritance has been resolved, and 
XSL-FO does not have a choose function.

 

In the XSLT stage, you can test for various ancestor elements that you know 
produce small type and take action there.

Hi

  
 

  
I have customised the registration mark handling like this:

  
 

  
<xsl:template name="dingbat">
  <xsl:param 
  name="dingbat">bullet</xsl:param>
  <xsl:variable 
  name="symbol">
    <xsl:choose>

  
[ snip ]

  
      <xsl:when 
  test="$dingbat='registered'">
        
  <fo:inline baseline-shift="super" font-size="75%" 
  inline-progression-dimension="100%">&#x00AE;</fo:inline>
      
  </xsl:when>
[ snip ]

  
</xsl:template>

  
 

  
All works well, but I want to extend this so that when the font size for 
  registration make is (say) less than 8pt then just output the registration 
  character without the superscript and font size reduction, as at some point it 
  becomes difficult to read. [ I have the (r) on both the cover page and in the 
  footer ].

  
 

  

  
The question is: how to test the active font size, so I can switch 
  behaviour accordingly?

  
 

  
Thanks.
