To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions.                                                                                                                                       |

This is needed if any of the data points have the value "L" (lower than detection limit).                                                                                                                                  |

This is needed if any of the data points have the value "U" (higher than detection limit).                                                                                                                                  |

If this value is greater than one, then the dimensions will be interlaced - all the sample points for a point in time will be recorded at once.<br>If there is more than one dimension, the code for the type of data will define the meaning of the dimensions (typically ECG data). |

The special values "E" (error), "L" (below detection limit) and "U" (above detection limit) can also be used in place of a decimal value.<br>Data may be missing if it is omitted for summarization purposes. In general, data is required for any actual use of a SampledData. |
