that's a missing feature (an important one IMHO). shouldn't this bug's severity be made major?
Just to ping this one again (to celebrate its 5th birthday). Actually, IMHO this should be quite a fast fix (although I have no clues of the Gecko internals, I might therefore be totally wrong). Why a fast fix? From my reading of the spec it seems as if <tref/> is nothing else than a <use/> in disguise, and the latter is almost fully implemented. The only difference is, that <use/> uses all referenced DOM elements while <tref/> uses all CDATA.
Some have lately blogged   about the wish to suppress this from SVG future. I also have never used this potentially neat feature, but mostly because of lack of support (if Firefox, at least). I'm not claiming that priority should be increased/decreased, I'm just throwing these links in the hope of being useful. :-) Actually, I find this feature interesting in the scope of declarative SVG (read: non-scripted) but potentially superseded by the params proposal  ?  http://berjon.com/blog/2010/01/svg2.0-wishlist.html  http://www.codedread.com/blog/archives/2010/01/29/svg-2-0-wishlist/#slicing-not-chopping  http://www.w3.org/TR/SVGParamPrimer/  http://www.w3.org/TR/SVGParam/
The SVG Working Group recently resolved to remove <tref> from the spec. http://www.w3.org/2014/05/08-svg-minutes.html#item02
