Adding to the point that Bob DuCharme made earlier: In XML Schema, it is
not illegal to reference or declare (as a local declaration) an element within
multiple "content models" (an example of a content model would be your
<chapters> element and its subelements and any attributes). One approach
within XML Schema would be to declare a global element <name> and
reference it in the multiple content models (IMHO, this is the best approach
versus re-declaring the element multiple times as a local declaration).
If, for some reason, the format of a global element <name> is
different within the <subsection> content model than it is within the
<chapters> content model (for example, a subsection name may be max 30
characters while a chapter name may be max 20 characters), one would could
reference the global element <name> within the <chapters> content
model, and declare a local element <name> within the <subsection>
content model - or vice versa.

Hi all,
According to the XML specification, I believe the
following nesting structure to be invalid in XML. However, rxp on my
Windows machine issues no warnings to me when parsed. Is this in fact
invalid?
<?xml
version="1.1"?>
<library>
<book>
<title>Book
Name</title>
<chapters>
<name>first
chapter</name>
<name>second</name>
...
<name>last</name>
<subsection>
<name>I
expect this to be illegal, since name is defined in chapters, and also somewhere else in its content, namely
subsection.</name>
</subsection>
</chapters>
</book>
</library>
Thanks very much,
Dan
