I think that means that the content of the title element which is a child of the head element which is a child of the html element which is the document element should be reflected as the title attribute of the document, and vice versa. Nowhere it says it is "the title of a document as _originally_ specified by the TITLE element". Reproducible: Always Steps to Reproduce: 1.Change document.title and look at the content of the <title> element. It's not changed. 2.Change the content of the <title> element and look at document.title. It's not changed. Actual Results: Changing document.title does not change the content of the <title> element, and vice versa. Expected Results: Reflected any changes in the child nodes of the <title> element in document.title and reflected any changes in document.title in the child nodes of the <title> element. Removing the <title> element should set document.title to the empty string. Mozilla won't let anyone put two <title> elements in the head (I checked).
