Especially for use in "child pages" (e.g. options) for respective "parent pages" (e.g. decisions), I may want to include some property of the parent page in some page property value of the child.
Example: Assume you have a page property called prio at each parent page and also at each child page. However, the value at the child pages you really want to be computed as: <parent-prio>.<child-prio>, so you can neatly sort on that column later.
Now, what you don't want to do at all children is to manually enter the value for <parent-prio> and keep that updated whenever the parent prio changes. Instead, you want to be able to include said property from the parent and display its current value at the child.
Beyond custom page properties, including standard properties of a page should also be supported, e.g. labels, creator, created, modified, modified, excerpt, etc...
In other words, I am asking for some more powerful macro than "Excerpt Include", e.g. some "Property Include" where the Excerpt is but one of the (standard) properties that are supported.
In any case, thanks for an awesome wiki system.
