I need a pointer or two about creating a schema. I have a situation where the incoming XML will have an element/attribute specifying one of four enumerated choices. Depending on the value of that choice, the elements that follow will be different. Like this: <foo> <mode>one</mode> <data1>aaa</data1> <data2>bbb</data2> </foo <foo> <mode>two</mode> <data3>ccc</data3> <data4>ddd</data4> </foo> or <foo mode="one"> <data1>aaa</data1> <data2>bbb</data2> </foo <foo mode="two"> <data3>ccc</data3> <data4>ddd</data4> </foo> How does one set up the schema to validate the appropriate sequence of elements based on the value of the "controlling" element/attribute ? Thanks in advance.
