Attribute parameters get evaluated and PRINC'd, so you don't need the
quotes around the numbers:

CL-USER: (cl-who:with-html-output-to-string  (s nil :indent t)
           (:agent-3d-view
            :name "scene"
            (:cube :texture "crate.png")
            (:sphere :x 2.0)
            (:sphere :x 3.0 :texture "earth.png")
            (:cube :size 3.0 :z -3.5 :texture "crate.png")
            (:cube :x 5 :roll 45.0)
            (:sky-dome :pitch 90)))
