Copying over two issues from the spec:
The strict exclusion of non-rendered metadata elements, including desc,
from the accessibility tree
means that their content will only be available as plain text,
not as structured alternative representations
that a user can navigate in browsing mode.
This contradicts the original intent of the SVG specifications,
which allows these elements to include structured content,
including HTML-namespaced content.
The SVG 1 specifications had suggested that this could
be alternatively presented as CSS-formated XML text,
but this is not supported by the
user agent/assistive technology combinations
currently in use.
The CORE-AAM section on Relations requires that assistive technologies SHOULD provide a method to navigate to (and within) structured content referenced by aria-describedby. This would be difficult to implement with the current approach of not including non-rendered descriptive content in the accessibility tree. See w3c/core-aam#3
