There was a proposal at one time that named anchors (like what
occurs after a #) might be defined per media type.

text/html defines what #xxxxx means: look for <A NAME="xxxxx"> in the
	referenced object.

so

application/tar   might define that #xxxxxxx means "look for a
	subpiece of this entity whose file name is xxxxxxx".

The only tricky parts are dealing with the character set issues.

None of this has been written up in an Internet-Draft or experimental
RFC though.
