My first question whether that is enough and whether we need to consider double quotes , the percent sign and curly brackets.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I had initially thought that it would probably be safe to make this a constraint but I can certainly see that there may be attributes flowing from data connectors from badly created data stores (example: "User's name") so I think we need to warn in V4.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">Regardless I was shocked when I went into the V3 source and discovered that the check wasn't in <tt>IdPAttribute</tt> (which is where there is a constraint in V4). This is because V3 is a different world and Attribute names only have any importance once they issue from AttributeResolvers. So the warning is on the attribute definition - which is the correct place. Attribute which occur with spaces outside this world are OK because they can never impact on the flows.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In V4 attributes can go through the complete flow and never see the attribute definition and so the (new) deprecation warning needs to be in the IdPAttribute (as well as attribute definition and potentially transcoders - see below). Further in IdPAttribute we need a debug level message with the attribute name to help diagnose these (since we are much further from the configuration at this point),</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">So I'll add the test for a single quotes. What does the team think about other special characters? Obviously we cannot disallow '.' and ':' but there are others.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0"> </p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">Finally I should note that in V4 the constaint in IdpAttribute is</p>
