Answer 1

1.Is the XML formatting correct?

Yes, however do note that a processing instruction does not have attributes -- only data. What looks like attributes are part of the data and some people call them "pseudo-attributes".

2.Is this the proper way to go about parsing processing instructions using the StAX XMLStreamReader APIs?

Yes.

3.How do I use getPITarget() and getPIData() to return multiple arguments?

If by "multiple arguments" you mean the possibly more than one pseudo-attributes contained in the data, the answer is that your code must parse the data (using some standard string methods as the C# split(), and retrieve the set of name-value pairs for all pseudo-attributes.
