Greetings

My goal is to implement in Inkscape the equivalent behaviour of "glue" as found in Visio. In Visio this is exhibited by creating two "lines" and then dragging the end point of one line to coincide with the end point of the other. The behaviour of these "lines" are defined such that when a "coincidence" event occurs the end points are "glued", ie a transformation of one of the lines (e.g a translation) causes the end point of the other line to continue to coincide with the position of the other end point (i.e the end of one line "follows" the position of the other).

It would be nice if,  within Inkscape, I could specify such behaviour, but its absence would not be fatal  because I have other means of specifying the content of the SVG that would be input to Inkscape.

Firstly,  are there any elements within the SVG specification that would naturally allow this behaviour to be defined?.  Unfortunately I am not in a position to specify the glued coordinate as one that is part in a single polyline. I am constrained by a requirement that this behaviour be exhibited between two distinct geometric elements. I initially had in mind providing an identifier for one of the points in one polyline. I could then define a point in the other polyline as a reference to this identifier. But I dont think SVG's element and attribute structure allows this.

Secondly, if the SVG specification supported such a semantic, would Inkscape reflect this in its behaviour. That is, if (to take one possible solution) one point were defined as a reference to the other, would Inkscape know to update all points that were defined by reference.

Thanks in advance for any assistance
