ANCS Attribute max length

[Matt]

We found that the ANCS Attribute max length is 99, and the last three characters is "...". Is the ANCS or Nordic SD limitation?

set BLE_ANCS_ATTR_DATA_MAX 128, the max of evt.attr.attr_len is 0x63 even the iPhone received more than 100 characters, the last three data are '\x2e,\x2e,\x2e'('...').
