で話題にしたSVG（Scalable Vector Graphics）は、説明パネルなどでフォントサイズや文字の位置をインワールドで編集できる便利なものです。
Firestormで日本語が文字化けするのを修正したものを知世さんが作ってくれたのですが、以下のデータだとエラーが出ます（元のバージョンでは正常表示）。tspanを使わないデータではエラーは出ないです。

//
// The demo script below, adapted from the Notecard on a Prim script, reads a notecard with SVG elements and puts it in the URL. This is limited to 1024 characters. Remember to create a notecard inside the prim for this to work.
//
// Unfortunately, SVG is more trickier to handle when trying to embed it into a web page via the same prim. Using the other techniques like Ajax to increase the size is running into problems. To embed SVG into a page requires the use of the Object / Embed tags. It has no problems linking to an external website with the SVG file. But trying to reference a prim via HTTP-In to get the SVG code, is not working at all. The only way around that I can see would be to have IFrames and embed the "Data:image/svg+xml" Mime type encoding of the SVG in the Iframe source path.
