Subject [Xmlgraphics-fop Wiki] Update of "PropertyHandling/PropertyCache" by AndreasDelmelle
Date Thu, 08 May 2008 15:38:10 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Xmlgraphics-fop Wiki" for change notification.

The following page has been changed by AndreasDelmelle:
http://wiki.apache.org/xmlgraphics-fop/PropertyHandling/PropertyCache

------------------------------------------------------------------------------
  
  Note: a fact overlooked by many is that, according to the XSL-FO Recommendation, '''any'''
property may be specified on '''any''' formatting object. The fact that the font-size property
does not apply to {{{fo:root}}} still does not mean that the property will be entirely lost.
Due to regular inheritance, '''all''' {{{PropertyList}}}s will ultimately use the value of
the root {{{PropertyList}}} unless an override is provided on a deeper level.
  
- Still, sometimes this type of streamlining of the stylesheet is not always possible. In
contexts where the stylesheet is generated by a third-party tool, there are likely to be many
XML attribute specifications that, from the point of view of the formatter would be redundant.
On another note, there are also many {{{<enum>}}} properties that share the same possible
values, but are not inherited.

  The initial idea for further optimization in that area was given to FOP by Richard Wheeldon
in a Bugzilla patch (see: https://issues.apache.org/bugzilla/show_bug.cgi?id=41044).
