Hi Folks,

Suppose a <Beverage> element has multiple ancestor elements with an inheritable attribute, start-time. The <Beverage> element has an <assert> or <alternative> element that references start-time. Which start-time applies?

Example: Suppose each start-time attribute is inheritable:

--------------------------------------
<Conference start-time="08:00:00">

    <Meeting start-time="13:00:00">
        
        <Beverage>Juice</Beverage>

    </Meeting>

</Conference>
--------------------------------------

Suppose <Beverage> has an <assert> element:

    <assert test="@start-time lt 12:00:00" />

If the <Meeting> element's start-time applies then the instance data is invalid.

If the <Conference> element's start-time applies then the instance data is valid.

Which start-time applies?

/Roger
