Re: [xep-support] SVG questions/problems

Hi Mats,

SVG has a direct declaration of the font family, while text in other
parts of the document has no such a declaration -- i.e. it uses a
default font family.

Remove the 'font-family:serif' from SVG or set this attribute to those
font family that has all desired glyphs.

It's a limitation of SVG support in XEP -- XEP processed only text
children of the svg:a element.

Put the @baseline-shift attribute on the corresponding 'text' element.
The value of -25% will give you desired effect for all font sizes.

Bob has already answered to this.

If you format your sample to XSL-FO, you will notice that there is an
fo:external-graphic element with an empty url.

You may ask about this issue in DocBook list
(docbook-apps@lists.oasis-open.org).

XEP does not support ligaturization in SVG.
