IMPORT_TRANSFORM_STRIP

Don't use this feature. It was added for a very specific situation at Stack Overflow.

IMPORT_TRANSFORM_STRIP is the same as IMPORT_TRANSFORM with an additional parameter: suffixstrip.

When IMPORT_TRANSFORM_STRIP is generating the label for new records, it checks the label. If the label ends with . + suffixstrip, that suffix is removed. If the label does not end with suffixstrip, an error is returned.

For CNAMEs, the suffixstrip is stripped from the beginning (prefix) of the target domain.

For example, if the domain is com.extra and the label is foo.com, IMPORT_TRANSFORM would generate a label foo.com.com.extra. IMPORT_TRANSFORM_STRIP(... , 'com') would generate the label foo.com.extra instead.

In the case of a CNAME, if the target is foo.com., the new target would be foo.com.extra.
