The SVG has a linear "opacity" gradient along a circle.
I mean gradient applied to opacity property, not color as in "normal"
gradient.

It's the 'stop-opacity' attribute on the
'linearGradient'/'radialGradient' elements that forms an "opacity" gradient.
The current version of XEP does not support the 'stop-opacity' attribute.

The support of the 'stop-opacity' attribute is in our TODO list.
Moreover, implementation of the basic level support for this attribute
is in progress now.
I hope the next major release of XEP will include the support of the
"opacity" gradients.
