If the first note of your report refers to the corporate information, we understand that the mandatory mark ups related to the company data (name of the reporting entity, address, etc.) cover the tagging of this block text. There is no tag or element that would fit this section apart from the separated elements present in the Table 1 of the Annex II of the RTS.
If the information of this first note refers to something else that needs to be tagged the same way as the rest of the notes, then we recommend you to find alternative places in your report to place hypertags that are tied to your general data.
Remember that you should only hypertag your general data once.
