Hello,
Nigel McFarlane has written an article for the DevX
site titled "A Standards-based Look at XAML's
Features" that looks how Microsoft's upcoming Avalon
XAML differs from public W3C standards such as CSS2,
SVG or XHTML.
The contents includes:
* XAML vs. CSS2
* XAML, XUL, and XHTML Overlap
* XAML and XUL Windowing Features
* XAML and SVG Overlap
* XAML's Unique Tags
Nigel concludes:
A tag-by-tag comparison of XAML with other XML
standards is just a beginning. For simple uses, and
even for some intermediate ones, such a comparison
might be all you need. For more complex uses, though,
there's a lot more to the comparison of XML GUI
dialects. In the bigger picture, Microsoft's Avalon
display system integrates the XAML tags together far
more tightly than any other XML display system so far.
This is most obvious in the SVG-like two-dimensional
effects that XAML can apply to XUL-like widgets and to
XHTML-like content. Although Mozilla allows deep
integration between SVG, CSS, XHTML, and XUL, it
doesn't yet go as far as XAML in applying the
processing tricks of one standard to all the tags of
all the others. Then again, XAML's support for CSS, by
comparison, is nonexistent. The unifying approach that
CSS brings to various W3C standards is sorely missed
in XAML by this writer. If XAML presented a substitute
styling system that was as integrated as CSS, then
XAML would be another matter—at least then we could
have a proper technology shoot-out.
Examined superficially, XAML tags have many of the
features of traditional Web standards like HTML, as
well as those of newer Web approaches like Mozilla's
XUL. Alas, it lacks proper CSS stylesheet support.
Examined more deeply, however, XAML tags reuse,
reinvent, and renew many standard idioms from the
software development world in a highly integrated way.
