No, there is a trailing "*" in "any-attribute = attribute * {text} *"
which apply to the whole attribute.

I guess that this pattern should be called any-attributes instead of
any-attribute :) .

any-attributes = attribute * {text} *
any-element = element * { any-attributes, any-content }

Unless you prefer to move the trailing star to the reference:

any-attribute = attribute * {text}
any-element = element * { any-attribute *, any-content }
