<br><font size=2 face="sans-serif">A couple more comments:</font>
<br>
<br><font size=2 face="sans-serif">- I think that declaring a targetNamespace
without binding it to a prefix, coupled with binding the empty prefix "xmlns"
to the xsd subset namespace, might cause problems. </font>
<br>
<br><font size=2 face="sans-serif">- I think the two 'sep' variables should
have a default value, then the absolute and relative xsds could be used
in their own right, without envelope.</font>
<br>
<br><font size=2 face="sans-serif">Here's my simpler version of the example
so far, look in the 'markup' folder. Changes made implement my various
comments, plus assign the 'sep' and 'msgKind' variables the same simple
type as I've created for the corresponding elements (part of action 028).
More to come.</font>

<br><font size=2 face="sans-serif">Some comments on your example (note
I used the updated .zip in your other mail). </font>
<br>
<br><font size=2 face="sans-serif">- The number of variables make it harder
than it needs to be to understand - see later comments.</font>
<br>
<br><font size=2 face="sans-serif">- I think it would have been clearer
if the setting of 'sep' and 'msgKind' was symmetric, I would set
the two 'sep' variables on the 'dirPathSep' element.</font>
<br>
<br><font size=2 face="sans-serif">- The encoding could be constant to
makes things simpler.</font>
<br>
<br><font size=2 face="sans-serif">- It would have helped if you
had defined 'msgKindType' simple type with enums 'A' and 'R', and a 'dirPathSep'
simple type with enums '/' and '\'.</font>
<br>
<br><font size=2 face="sans-serif">- For this example, it would be clearer
if 'dirPathSep' and 'msgKind' were not set via outputValueCalc and their
values were just provided by the infoset. Given that they are not hidden
this makes more sense. If you want to set them using outputValueCalc then
I would suggest that you make the entire header hidden.</font>
<br>
<br><font size=2 face="sans-serif">- I'm not sure that the modelling of
the paths works. The file name will be consumed by the pathPart element,
because the delimiters are prefix/infix. I think you need to use postfix
separators or terminators. With postfix separator, failure to find the
separator when matching the last part to 'pathPart' will cause a backtrack,
and we will then try and (correctly) match the last part to 'file'. Note
that there is just one sequence when you do it this way, as the separator
also applies to 'driveLetter'.</font>
