Table Notes

[1](1, 2, 3, 4, 5) The unit attribute is required. See Rules for acceptable values.
[2]While \(z\) is allowed by the standard (provided by use of a standard size element in the XML Schema), it does not make sense to use it for small-angle scattering. Use of \(z\) here may be ignored by processing software.
