Ω: the membrane factor the beam method (FHWA GEC-13 Eq. 3-26,tabulated against strain in Table 6-2, Young et al. 2003) multipliesthe load carried by this layer and half the design span by to obtaindesignTension, where the more general parabolic method (Eq. 3-25)instead solves for tension from tensileStiffness and atStraindirectly. It is a method-specific input to that output, not abreakdown of it, and is specific to the FHWA beam method: BS 8006-1(Eq 3-16) and EBGEO (Eq 3-20) obtain tension as tensileStiffnesstimes strain directly, and the ASIRI unit-cell method does notcompute geosynthetic membrane tension at all. It is a plain measuretype, not an authorized parameter, because its name alone identifiesit. Nothing in the schema links this value to the method thatproduced it, and nothing prevents populating it alongside a designthat otherwise used BS 8006-1 or EBGEO; state the method in remarkor in the designMethod of the design's basis(diggs:RIProgramBasisType, through basisRef), as fordiggs:DesignRILTPType/criticalHeight and the arching model.

Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
