Does this need to be a PassRefPtr? Probably Document* ?

[tasak, 2014/11/19 09:23:03]

This code is the same as the original code:
PassRefPtrWillBeRawPtr<Document> transformSourceDocument() { return
m_transformSourceDocument; }

[haraken, 2014/11/19 09:33:59]

ok, but this looks not nice. Given that transformSourceDocument() is not passing
an ownership of the document, it should be Document*.

[tasak, 2014/11/19 11:12:35]

Done.

+        return m_transformSourceDocument;

+
+    void setTransformSourceDocument(Document* document)

+    static const char* supplementName();

+    // The following static methods doesn't use any instance of DocumentXSLT.

[haraken, 2014/11/19 09:01:36]

doesn't => don't

[tasak, 2014/11/19 09:23:03]

Done.

+    // Just they are just using DocumetnXSLT namespace.

[haraken, 2014/11/19 09:01:36]

Just they are => they are

[tasak, 2014/11/19 09:23:03]

Done.
Also fixed Documetn => Document
