Hello,

Is there a way to process a document such as the one below, without getting a warning?

The difficulty here is to mix shell variables (using the ${var} notation is a requirement) with asciidoctor attributes in the same block. The final output is fine, but I am getting a lot of warnings and sorting out which ones matter (actually missing asciidoctor attributes) and which one don't (shell variables) is not always easy.

# Test

:attribute-missing: warn

:ADOC_ATTR:      asciidoctor

[subs="attributes"]
----
SHELL_VAR="shell"

echo {ADOC_ATTR} ${SHELL_VAR}
----

In this case, the output is:

asciidoctor: WARNING: skipping reference to missing attribute: shell_var

Thanks.
