| statutes and treaties. First, as discussed above in Comment 5, |
| it leaves the determination of some rules, such as the rule |
| establishing time of perfection (Section 9-516(a) [Maine cite |
| section 9-1516, subsection (1)]), to the other statutes |
| themselves. Second, this Article explicitly applies some Article |
| 9 [Maine cite Article 9-A] filing rules to perfection under other |
| statutes or treaties. See, e.g., Section 9-505 [Maine cite |
| section 9-1505]. Third, this Article makes other Article 9 |
| [Maine cite Article 9-A] rules applicable to security interests |
| perfected by compliance with another statute through the |
| "equivalent to . . . filing" provision in the first sentence of |
| Section 9-311(b) [Maine cite section 9-1311, subsection (2)]. |
| The third approach is reflected for the most part in occasional |
| Comments explaining how particular rules apply when perfection is |
| accomplished under Section 9-311(b) [Maine cite section 9-1311, |
| subsection (2)]. See, e.g., Section 9-310 [Maine cite section 9- |
| 1310], Comment 4; Section 9-315 [Maine cite section 9-1315], |
| Comment 6; Section 9-317 [Maine cite section 9-1317], Comment 8. |
| The absence of a Comment indicating that a particular filing |
| provision applies to perfection pursuant to Section 9-311(b) |
| [Maine cite section 9-1311, subsection (2)] does not mean the |
| provision is inapplicable. |
