What is the correct syntax for XSD to restrict attrributes values in the elements list?
- by Leonard
What is the correct syntax for XSD schema to define the following restriction:
In the list of elements we have to specify that attribute can contain value of "c" unlimited number of times, but value of "b" - the zero or only one time.
For example, the correct xml looks like this:
<root>
<elem atr="c">111</elem>
<elem atr="c">222</elem>
<elem atr="b">333</elem>
<elem atr="c">444</elem>
<elem atr="c">555</elem>
</root>
And incorrect one is:
<root>
<elem atr="c">111</elem>
<elem atr="c">222</elem>
<elem atr="b">333</elem>
<elem atr="c">444</elem>
<elem atr="b">555</elem>
</root>
