I assume this refers to svg:stroke-linecap 
(§20.164 in the ODF 1.2 spec, which refers to 
stroke properties in the SVG spec: 
<http://www.w3.org/TR/SVG11/painting.html#StrokeProperties>).

SetAccessibleName is a method that exists in several accessibility APIs, e.g.
* ATK: atk_object_set_name: 
<http://developer.gnome.org/atk/stable/AtkObject.html#atk-object-set-name>
* Java: 
<http://download.oracle.com/javase/6/docs/api/javax/accessibility/AccessibleContext.html#setAccessibleName%28java.lang.String%29>
* Microsoft: 
<http://msdn.microsoft.com/en-us/library/bb776383.aspx>: 
"IAccessibleObject::SetAccessibleName method"

I don't know what the "accessible name" for a 
stroke-linecap would be (i.e. when it is present 
in ODF content). However, if you are referring to 
a list box where an author can choose between 
different stroke-linecap styles, I would 
definitely give those options an accessible name 
(e.g. butt cap, round cap and square cap, which I found in the SVG spec).


I hope this helps.

Best regards,

Christophe
