- Legacy data is best transformed into presentation markup
- Authoring tools may prefer presentation markup
- Authors have less control on final appearance with content markup
-
High quality renderers may prefer to use content markup:
- difference between an inline vs standalone formula
-
differences in local traditions, disciplines:
- 3+4i resp. 3+4j!
- Pedagogic tools would use content markup
- Content markup can be used to transfer abstract information
- Content markup is more accessible
The two markups may be mixed (see examples later)!
