Section 2.3.2.1 says:
For IDNA-aware applications, the three types of valid labels are "A-labels", "U-labels", and "NR-LDH labels", each of which is defined below.
It should say:
For IDNA-aware applications, the three types of valid labels are "A-labels", "U-labels", and "NR-LDH labels", each of which is defined below and in section 2.3.1.
Notes:
The term NR-LDH label is actually defined in section 2.3.1, not later in this section.
[Note from the document author: In reality, at least from the author's perspective, "NR-LDH label" is defined in the section of that name, i.e., 2.3.2.2, which is "below" 2.3.2.1. Whether 2.3.1 also "defines" it or supplements that definition (or if 2.3.2.1 supplements what 2.3.1 has to say) is a matter for debate, but it is clear that the text cited would benefit from a reference to 2.3.1.]
