!ENTITY being stripped

Your svg cleaner strips out the ENTITY and (I presume) DOCTYPE for security reasons.

Is there a way I can have it allow those elements to stay (even if temporarily) for a file I created and know is safe?

these 3 elements specifically are what I am trying to keep, so possibly if entity url value is adobe.com, then keep those entities?

<!ENTITY ns_extend “https://ns.adobe.com/Extensibility/1.0/”&gt;
<!ENTITY ns_ai “https://ns.adobe.com/AdobeIllustrator/10.0/”&gt;
<!ENTITY ns_graphs “https://ns.adobe.com/Graphs/1.0/”&gt;
