says:
For example, the following snippet:
<label> Part number:
<input pattern="[0-9][A-Z]{3}" name="part"
title="A part number is a digit followed by three
uppercase letters."/>
</label>
...could cause the UA to display an alert such as:
part number is a digit followed by three uppercase letters.
You cannot complete this form until the field is correct.
which is missing the "A" in the last-but-one line.
