2.2.12.2 Emitting Instruction for the Attribute Rule

Before emitting anything, the tool SHOULD verify that the attribute data, as specified by the AttributeCharData rule in 2.2.12, is not empty. If the attribute data is empty, the tool SHOULD NOT emit anything. If the attribute data is not empty, emit the space character " " and the text, as specified by the Name rule in 2.2.12, the character "=", the character "'", the text, as specified by the AttributeCharData rule in 2.2.12, and, finally, the character "'".
