S-101 Product Specification describes invalid C3DI field.

[FrankHippmann]

S-101 Product Specification s. B-6.1.14 describes a C3DI field, which is not defined by S-100. It should be C3IT.

As a further note, S-100 s. 10a-6.2.2.2 Coordinate Reference System Header field structure references undefined fields: C3DI or C3DF. It is likely that C3IT and C3FT is meant here.
