A seal for sealing a space defined by first and second components, the seal comprising: a first seal section including a first base and a first leg extending from the first base;a second seal section including a second base and a second leg extending from the second base; wherein the first and second seal sections are configured to sealingly engage with the first and second components;wherein the first and second seal sections are configured to move relative to one another; anda tab including a tab body, a first tab end and a second tab end, wherein the first seal section defines a first opening, the second seal section defines a second opening, the first tab end is disposed in the first opening, and the second tab end is disposed in the second opening. 2. The seal of claim 1, wherein the seal is formed from a material selected from one of a high-temperature metal alloy, a high-temperature ceramic fiber material, and a high-temperature ceramic fiber composite, or a combination of two or more of a high-temperature metal alloy, a high-temperature ceramic fiber material and a high-temperature ceramic fiber composite. 3. The seal of claim 1, further comprising: a coating applied to at least a portion of each of the first and second seal sections. 4. The seal of claim 1, further comprising: a sheath covering at least a portion of each of the first and second seal sections. 5. The seal of claim 1, wherein: the first and second seal sections are substantially annular. 6. The seal of claim 5, wherein the first and second seal sections respectively define first and second gaps at respective opposed ends thereof. 7. The seal of claim 6, further comprising a bridging seal disposed adjacent the first and second seal sections and at least partially covering the first and second gaps. 8. The seal of claim 1, wherein the first and second seal sections together define a substantially frustoconical cross-section. 9. The seal of claim 1, wherein: the first tab end forms a first angle with the tab body; and the second tab end forms a second angle with the tab body. 10. The seal of claim 1, further comprising a rope seal disposed between the first and second seal legs. 11. The seal of claim 10, wherein the rope seal is annular. 12. The seal of claim 11, wherein the rope seal defines a gap at opposed ends thereof. 13. The seal of claim 1, wherein the first base is disposed adjacent the second base. 14. A system, comprising: a first component including a first surface;a second component including a second surface, the second component disposed adjacent the first component and defining a seal cavity therebetween; anda seal disposed in the seal cavity, the seal including:a first seal section; and a second seal section; wherein the first and second seal sections are configured to move relative to one another; wherein pressure within the seal cavity urges the seal to seat against the first surface and the second surface; andwherein relative movement of the first component and the second component toward or away from one another causes the first and second seal sections to slide relative to one another such that the seal is not substantially deflected; anda tab including a tab body, a first tab end and a second tab end, wherein the first seal section defines a first opening, the second seal section defines a second opening, the first tab end is disposed in the first opening, and the second tab end is disposed in the second opening. 15. The seal of claim 13, wherein: the first seal section includes a first base and a first leg extending from the first base; and the second seal section includes a second base and a second leg extending from the second base. 16. The seal of claim 15, wherein the first base is disposed adjacent the second base. 17. The seal of claim 14, wherein the seal is formed from a material selected from one of a high-temperature metal alloy, a high-temperature ceramic fiber material, and a high-temperature ceramic fiber composite, or a combination of two or more of a high-temperature metal alloy, a high-temperature ceramic fiber material and a high-temperature ceramic fiber composite. 18. The seal of claim 14, wherein: the first and second seal sections are substantially annular. 19. The seal of claim 18, wherein the first and second seal sections respectively define first and second gaps at respective opposed ends thereof. 20. The seal of claim 19, further comprising a bridging seal disposed adjacent the first and second seal sections and at least partially covering the first and second gaps. 21. The seal of claim 14, further comprising a rope seal disposed between the first and second seal legs.
