(b) A respondent may under Section 56.01, Family Code, appeal a juvenile court's order under Article 62.352(a) requiring registration in the same manner as the appeal of any other legal issue in the case. The standard of review in the appellate court is whether the juvenile court committed procedural error or abused its discretion in requiring registration.
