PIs are for passing procedural instructions through XML to a
post-processor.  They are not intended for consumption and
action by the XML processor itself in any way that would affect
the integrity of the document. 

For example you can encode a forced  line-break in a title that
you know will be required when the document is typeset but which
you don't wish to hard-code wrt the document structure:

<title>How I Made <?LaTeX \\?>A Million Dollars</title>
