No, I was talking about how presentational properties are tacked to
nodes in the XML tree. Usually nodes inherit certain properties from
their ancestors. Two problems:
- Which properties are inherited, and where is inheritance blocked.
- The interaction of inheritance, shorthand evaluation and default
values.
- If the properties are declared separately and connected to the tree
by a matching mechanism, it has to be defined how this is done. For
example
div.sect { margin-top: 3pt }
div { margin: 12pt }
Unfortunately, CSS mixes all aspects and thereby muddles what
"inheritance" means.
As for your thoughts, well, XSLFO introduced structured properties
consisting of minimum, optimum and maxumum values and occasionally
of a conditionality, with shorthands for setting all values at once,
and with shorthands to set a bunch of related properties, and an
expression language, and a variety of data types. This introduces a
lot of complexity, you can read a hairrising discussion about this
topic in the archives of the fop-dev list.
