@trost,
By default, attribute values are not recomputed. Therefore, reassigning fruit has no affect on phrase because phrase has already been resolved.
I looked into deferring the resolution of the attribute references when defining the attribute. To do that, you would use:
:phrase: pass:c[{fruit} is a kind of fruit]
While that prevents the attribute reference from being resolved at assignment, there's no way in AsciiDoc to have it be resolved later (aside from writing an extension*). The problem is, when you reference {phrase}, it only resolves the value of phrase, not the attribute references it contains.
Unless there's something I'm not thinking of, I don't think there's a way to do what you want to do currently. AsciiDoc attributes weren't designed for that use case. We could consider a way to recursively resolve attribute references after Asciidoctor 2.0.0.
Cheers,

You could write an inline macro extension called "resolve-deep" (e.g., resolve-deep:phrase[]) that resolves attribute references inside of an attribute value.

Hello--
I am having trouble finding information about something you might call "nested references" in Asciidoc--i.e., a user attribute reference that points to a value that contains another user attribute reference. In particular, I want to be able to reset the value of the lower-level reference and then have that new value be rendered by the upper-level reference without having to also reset the value of the upper-level reference, if that makes sense.
To illustrate the problem, consider the following example:
:fruit: orange
:phrase: {fruit} is a kind of fruit.
{phrase}
In this simplistic example, Asciidoctor would render "orange is a kind of fruit".
But, if I wanted to reset the value of "fruit"...
:fruit: orange
:phrase: {fruit} is a kind of fruit.
:fruit: apple
{phrase}
...Asciidoctor will still render "orange is a kind of fruit". I want Asciidoctor to reset the value of "fruit" within the "phrase" value, without having to explicitly reset the "phrase" attribute after the "apple" line. Is that kind of functionality supported?
