| * cases there may be more than one instance of a section type. |
| * |
| * The only two required sections for every type of PEL are the Private Header |
| * section and User Header section, which must be in the first and second |
| * positions, respectively. |

| * Every section starts with an 8 byte section header, which has the section |
| * size and type, among other things. |
| * |
| * This class represents all sections with objects. |
| * |
| * The class can be constructed: |
| * - From a full formed flattened PEL. |
| * - From scratch based on an OpenBMC event and its corresponding PEL message |
| * registry entry. |
| * |
| * The data() method allows one to retrieve the PEL as a vector<uint8_t>. This |
| * is the format in which it is stored and transmitted. |
