Use standard form as title for expressions without title
Currently, the standardized form isn't saved as a title in the MEI... but it was previously possible to save expressions without title because this form is automatically generated.
This can be used instead of a title... like
<title type="uniform">I am a title</title>
E.g.: https://corpus-musicae-ottomanicae.de/cmo-test/receive/cmo_expression_00004327 See MEI https://corpus-musicae-ottomanicae.de/cmo-test/receive/cmo_expression_00004327?XSL.Style=mei
