marker-end remove url (arrowhead dosen't appear)

Hello,

I need  to remove  url specified in the  marker-end attribute when generating SVG.

exemple:
marker-end="url(http://some url#arrowhead2)"   => dosen't work.
marker-end="url(#arrowhead2)"   => work.

I make search and i found that it have to be specified in configuration but i don't understand how.

thanks for your help
