Re: More on namespaces and XML schema...

Hello again,

Seeing as the link in the documentation (running under tomcat) for
lzx.dtd returns a 404 error I had to do a bit of searching around on the
net. There's a link on the wiki, under 'Editing LZX' that is also broken
too.

So initialy I tried using the XML Schema (lzx.xsd) and noticed
immediately:

1) That the form and window elements are not defined in the schema.



2) There are errors in the schema too:

In the definition of the element 'preloadresource' the name and resource
attributes are also declared elsewhere in attributeGroup declarations
referenced directly and indirectly by this element declaration.


3) If you put the appropriate markup, in the root of you canvas
document, to identify the schema:


<canvas xmlns="http://www.laszlosystems.com/2003/05/lzx"
        xmlnssi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.laszlosystems.com/2003/05/lzx
../schema/lzx.xsd"
        width="1024"
        height="768">
   ...
</canvas>


You get the following error message form the compiler:



The application could not be compiled due to the following errors:


Compilation Errors
form.lzx:10:22: Syntax error: the token ":" was not expected at this
position.
Compilation Warnings

form.lzx:10:22: attribute "schemaLocation" from namespace

"http://www.w3.org/2001/XMLSchema-instance" not allowed at this point;
ignored
form.lzx:10:22: found an unknown attribute named "schemaLocation" on
element canvas, check the spelling of this attribute name


This would suggest that not only is Open Laszlo not XML namespace aware
(see previous e-mail) but neither is it XML Schema aware either.



Its not that I'm being picky for picky's sake, I actually like what I've
seen of Open Laszlo so far. Its just that things I'd want and expect to
work don't.
