Is omitting the operation description for a Constructor ok in a sequence diagram?

[seraphimstreets]

As in image shown:

The majority of sequence diagrams in this course are shown with the constructor method call. Is it considered non-standard to omit it?

@seraphimstreets It is OK to omit it if omitting it doesn't introduce any ambiguity (w.r.t. the purpose of the diagram)
