Unfortunately, if we overlap hypertags, the engine could fail to recognize the desired information. This would lead to a blocking error in the validation report.
However, it is possible to use more than one tag on the same piece of text. For example, one note can be tagged with more than one tag . Please note that for this to happen, there will again be only one hypertag applied on the paragraph. But this hypertag will be modified to include all the tags we want to apply on this note. This process is called multi-tagging.
