RE: Leventhal's challenge misses the point

HI Guy,

Guy said:
It's interesting to note that the most recent progress in XPointer and XQL
have come from XSL. The reason? The power of XSL pattern matching syntax.

Didier says:
Right. good points about XSL:
- pattern match or location mechanism (help point to the right element)
- Event driven or rule based mechanism (suppress all the code for navigating
in the document)
- possibility to include elements in rules ( <BR> less than output "<BR>"
etc...)

bad points about XSL:
- some produced Ural constructs included in XSL do not fit well in a
declarative language

In fact, as long as XSL is declarative, it does a very good job and has a
major advantage to seamlessly integrate with XML or HTML constructs. When
XSL tries to be procedural it fail compared to the clarity of other
procedural language. the inverse is also true. When procedural languages try
to be declarative (within the constraint of keeping only procedural
constructs) it also do not fit well. I have not seen yet a language mixing
both procedural and declarative constructs elegantly.
