Aha, had not seen that file yet, thanks for the pointer.
But the same is true for the selection box you mention, have never come across 
that. Where in the UI can I see it (and thus the arrows in that file)?

Then the problem is that in XFig the arrow heads can be scaled independently 
in width and in length, and additionally have the concept of a stroke width, 
also settable per arrow instance.
Thus mapping of the XFig arrow shapes to the pre-defined in Calligra is only 
possible if I ignore the attributes length and stroke width.
For the latter I was thinking to ignore that anyway, as that seems to be only 
translatable in complicated ways which might not be worth it (at least for me, 
itches are to be scratched by those who need it :P ).
For the attribute length, well, could also for now ignore it, until people 
come and complain. I myself do not really need support for that as well.

OpenDocument does not predefine a set of arrow styles, or?

And the .soe format LibreOffice uses is their custom format, right?

Sure, thanks, doing so :)
