From the Release notes 0.47:
«Initial SVG Fonts support

As a SoC 2008 project, JucaBlues implemented initial parsing and rendering of SVG Fonts. You can design fonts within Inkscape, but using them to render text on the canvas is not yet supported. We are waiting for libpango to implement proper support of the user-fonts feature. »
