syntax error, unexpected TDOT invalid argument on gmn file generated from libmusicxml

[clyde-gustafson]

This is a gmn file converted from libmusicxml:

https://pastebin.com/iAzr6120

It works just fine with guidolib to render it, but when I try to load it into guidoar I get this error:

line 167 col 20: syntax error, unexpected TDOT
invalid argument

At that position there's a triple dot '...', but why is it that guidoar can't read it, but it was generated from libmusicxml and guidolib does just fine?
