public interface irunattrsource

the description here applies to all ixxxattrsource interfaces. in our model, different objects, for example style and paragraph, can both have paragraph formatting and it is exposed as paragraphformat to the public. the problem is that paragraph formatting on style and paragraph is resolved differently. for example, when getting an attribute from a style, it needs to look in the attributes of the style and then navigate through the based-on styles. when getting and attribute from a paragraph, need to look for direct formatting, then get the style of the paragraph and look for the attribute in the style. it is the purpose of ixxxattrsource interfaces to solve this problem and allow single paragraphformat to expose paragraph attributes to the public, yet allow variation in attribute resolution depending on what object paragraphformat is obtained from.
