  44.         The measure to be converted.

  46.         directly added to the number.
  47.  
  48.       PARAM 'rounding-factor'
  49.         Is used for the rounding of decimal places.
  50.         The parameter number is the product of 1 and some '10', where
  51.         every zero represents a decimal place.
  52.  
  53.         For example, providing as parameter:
  54.             <xsl:param name="rounding-factor" select="10000" />
  55.         Gives by default four decimal places.
  56.  
  57.         To round two decimal places, basically the following is done:
  58.             <xsl:value-of select="round(100 * value) div 100"/>
  59.  
  60.       RETURN    The converted number, by default rounded to four decimal places.
  61.                 In case the input measure could not be matched the same value is
  62.                 returned and a warning message is written out.

  66.      MEASURE LIST:
  67.      * 1 milimeter (mm), the basic measure
  68.  
  69.      * 1 centimeter (cm) = 10 mm
  70.  
  71.      * 1 inch (in) = 25.4 mm
  72.         While the English have already seen the light (read: the metric system), the US
  73.         remains loyal to this medieval system.
  74.  
  75.      * 1 point (pt) = 0.35277777.. mm
  76.         Sometimes called PostScript point (ppt), as when Adobe created PostScript, they added their own system of points.
  77.         There are exactly 72 PostScript points in 1 inch.
  78.  
  79.      * 1 twip = twentieth of a (PostScript) point
  80.         A twip (twentieth of a point) is a 1/20th of a PostScript point, a traditional measure in printing.
  81.  
  82.      * 1 didot point (dpt) = 0.376065 mm
  83.         Didot point after the French typographer Firmin Didot (1764-1836).
  84.  
  85.         More details under
  86.         http://www.unc.edu/~rowlett/units/dictP.html:
  87.         "A unit of length used by typographers and printers. When printing was done
  88.         from hand-set metal type, one point represented the smallest element of type
  89.         that could be handled, roughly 1/64 inch. Eventually, the point was standardized
  90.         in Britain and America as exactly 1/72.27 = 0.013 837 inch, which is
  91.         about 0.35 mm (351.46 micrometers). In continental Europe, typographers
  92.         traditionally used a slightly larger point of 0.014 83 inch (about
  93.         1/72 pouce, 0.377 mm, or roughly 1/67 English inch), called a Didot point
  94.         after the French typographer Firmin Didot (1764-1836). In the U.S.,
  95.         Adobe software defines the point to be exactly 1/72 inch (0.013 888 9 inch
  96.         or 0.352 777 8 millimeters) and TeX software uses a slightly smaller point
  97.         of 0.351 459 8035 mm. The German standards agency DIN has proposed that
  98.         all these units be replaced by multiples of 0.25 millimeters (1/101.6 inch).
  99.  
  100.      * 1 pica = 4.233333 mm
  101.         1/6 inch or 12 points
  102.  
  103.      * 1 pixel (px) = 0.26458333.. mm   (relative to 'DPI', here: 96 dpi)
  104.         Most pictures have the 96 dpi resolution, but the dpi variable may vary by stylesheet parameter
