A question about XPointer

Hi,

I would like to know if XPointer allows me to identify an XML attribute
of a resource fragment (not a resource fragment based on an attribute
value)? Is it possible? For example, may I refer to the title attribute
of a specific <A> element inside an HTML file?

Thanks for the help,
