Minimum nuimber of references in a template should be 1? #1

According to R2RML, in a string template "There SHOULD be at least one pair of unescaped curly braces.", i.e. at least one reference.

However, the YARRRML spec says "A template contains 0 or more constant strings and 0 or more references to data in a data". IMO the second 0 should be a 1, to be compliant w.r.t. R2RML.

I think that the template of YARRRML is not the same as the template of [R2]RML. A YARRRML template covers more than an R2RML template.

Thanks!
