Dear Till,
Yes, you're right. The equal sign "=" is also used in object languages all
over.
Can you give me a reference to EBNF that you have adopted, for I have
followed ISO's ebnf (1996) in producing ISO 24617-7:2014 ISOspace for the
annotation of (motion-involved) spatial information in a language.
Thanks in advance,
Kiyong
