Fonts not found on trunk build

Hello,

Using the 0.95 build and generating pdf, I can imbed a font by placing:

<font       kerning="yes"
           embed-url="fonts/OCR-A.ttf"
           encoding-mode="single-byte">
            <font-triplet name="OCR-A" style="normal" weight="normal"/>
</font>

In the foconfig.xml

When I build from trunk (I want to make use of the application/X-fop-intermediate-format that isn't available in 0.95)
The font is not picked up and a substitute is used.

Did the way to define fonts change in the trunk?  I cannot find any documentation in the fop site that would suggest this is the case.

Any help would be appreciated.

Regards,
Ken
