A Warning

<noscript> is both an inline and a block-level element. But, however <noscript> is used, it may contain only block-level elements. This strange rule means that a <noscript> used inline will assuredly make no sense structurally: in order to use <noscript> inside a paragraph, for example, an author needs to wrap the contents of <noscript> inside another paragraph, creating a nonsensical nesting. Thus, the only sane way to use <noscript> is as a block-level element.

<ruby>

The <ruby> element is a relative newcomer to the world of HTML. It is used for annotating spans of text, specifically, it is tradtionally used to give pronounciations for East Asian words. The <ruby> element is still quite rare, and it will likely become optional in future when the W3C reformulates XHTML with XML Schema Modules. The Ruby website gives more detailed infomation.
