If I may make some assumptions about what your problem is, here's my
thoughts.


I'm unclear on this point, myself, and would appreciate comments.
Given the document type declaration fragment
    <!ELEMENT outer (#PCDATA|inner)*>
    <!ELEMENT inner (#PCDATA)>
    <!ATTLIST (outer,inner) language CDATA #CURRENT>
and the document instance fragment
    <outer language=chinese>
	ha che
	<inner language=english>
	    good food
	</inner>
	kuluyuk
    </outer>
what is the value of the language attribute when "kuluyuk" is seen?

It seems clear that if the fragment ends with
	</inner>
	<inner>
	    sweet-sour pork
	</inner>
    </outer>
the second inner will have the language attribute value "english".


In the above case, the attribute only applies to 
the element that contains it. Therefore, in case (1) above,
kuluyuk is data within <outer language=chinese> and therefore
is treated as chinese. 

A case that may occur that is:


<outer language=chinese>
	ha che
	<inner language=english>
	    good food
	</inner>
	kuluyuk
</outer>
<outer>
	ha che
	<inner>
	    kuluyuk
	</inner>    
</outer>

where the second kuluyuk is going to be looked upon as english
since the last value of attribute language in element inner
was english.

What about making language a NOTATION ?

lets keep these discussions in news (rather than
private email) as it seems very useful in understanding
problems and solutions.
