<div dir="ltr"><div class="gmail_default" style="font-size:small">As you may know, I don't let the warning from vo-dml validation about open ended multiplicity bother me too much. Polynomial is another good example where it greatly limits/impacts how one might model something... I ran into it way back at point, circle, polygon (oops! non-fixed size). I don't expect this can be feasibly made illegal in future... I expect the warning/admoinishment to be softened, maybe with some good advice about when such cardinality is warranted and when another pattern may be a better choice.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">my 2c,</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"><br clear="all"></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div>--<br></div><div>Patrick Dowler<br></div>Canadian Astronomy Data Centre<br></div>Victoria, BC, Canada<br></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 9 Mar 2020 at 06:05, Gerard Lemson <<a href="mailto:glemson1@jhu.edu">glemson1@jhu.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
