Description

The coordinate order of the geographic reference position in the example for IfcRigidOperation [E.7.2 - Geographic Referencing Rigid Operation](https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/annex_e/placements-and-gis-referencing/geographic-referencing-rigid-operation.html) is incorrect. Accoring to [EPSG:4258](https://epsg.io/4258) the coordinate order is latitude, longitude.

Current coordinate order:
`#302=IFCRIGIDOPERATION(#21, #301, IFCPLANEANGLEMEASURE(14.0902217), IFCPLANEANGLEMEASURE(46.3623297), 475.);`

Corrected version:
`#302=IFCRIGIDOPERATION(#21, #301, IFCPLANEANGLEMEASURE(46.3623297)46.3623297, IFCPLANEANGLEMEASURE(14.0902217), 475.);`
