             in the instance, if the element has a value. Other additional values may be found
             too. This is effectively constraint by example.  

When pattern[x] is used to constrain a primitive, it means that the value provided
             in the pattern[x] must match the instance value exactly.

When an element within a pattern[x] is used to constrain an array, it means that
             each element provided in the pattern[x] must (recursively) match at least one element
             from the instance array.

When pattern[x] is used to constrain a complex object, it means that each property
             in the pattern must be present in the complex object, and its value must recursively
             match -- i.e.,

1. If primitive: it must match exactly the pattern value
2. If a complex object: it must match (recursively) the pattern value
3. If an array: it must match (recursively) the pattern value

If a pattern[x] is declared on a repeating element, the pattern applies to all
             repetitions.  If the desire is for a pattern to apply to only one element or a
             subset of elements, slicing must be used. See [Examples of Patterns](elementdefinition-exampl
            es.html#pattern-examples) for examples of pattern usage and the effect it will have.">pattern[x]</a>

      <definition value="Specifies a value that each occurrence of the element in the instance SHALL follow
       - that is, any value in the pattern must be found in the instance, if the element
       has a value. Other additional values may be found too. This is effectively constraint
       by example.  

When pattern[x] is used to constrain a primitive, it means that the value provided
       in the pattern[x] must match the instance value exactly.

When an element within a pattern[x] is used to constrain an array, it means that
       each element provided in the pattern[x] must (recursively) match at least one element
       from the instance array.

When pattern[x] is used to constrain a complex object, it means that each property
       in the pattern must be present in the complex object, and its value must recursively
       match -- i.e.,

1. If primitive: it must match exactly the pattern value
2. If a complex object: it must match (recursively) the pattern value
3. If an array: it must match (recursively) the pattern value

If a pattern[x] is declared on a repeating element, the pattern applies to all
       repetitions.  If the desire is for a pattern to apply to only one element or a
       subset of elements, slicing must be used. See [Examples of Patterns](elementdefinition-exampl
      es.html#pattern-examples) for examples of pattern usage and the effect it will have."/>

        A profile on a type can always make mustSupport = true if it is false in the base
       type but cannot make mustSupport = false if it is true in the base type.   This
       is done in [Resource Profiles](profiling.html#mustsupport), where the profile labels
       an element as mustSupport=true. When a profile does this, it SHALL also make clear
       exactly what kind of &quot;support&quot; is required, as this can mean many things.
          Note that an element that has the property IsModifier is not necessarily a &quot;key&quot;
       element (e.g. one of the important elements to make use of the resource), nor is
       it automatically mustSupport - however both of these things are more likely to

      <definition value="Specifies a value that each occurrence of the element in the instance SHALL follow
       - that is, any value in the pattern must be found in the instance, if the element
       has a value. Other additional values may be found too. This is effectively constraint
       by example.  

When pattern[x] is used to constrain a primitive, it means that the value provided
       in the pattern[x] must match the instance value exactly.

When an element within a pattern[x] is used to constrain an array, it means that
       each element provided in the pattern[x] must (recursively) match at least one element
       from the instance array.

When pattern[x] is used to constrain a complex object, it means that each property
       in the pattern must be present in the complex object, and its value must recursively
       match -- i.e.,

1. If primitive: it must match exactly the pattern value
2. If a complex object: it must match (recursively) the pattern value
3. If an array: it must match (recursively) the pattern value

If a pattern[x] is declared on a repeating element, the pattern applies to all
       repetitions.  If the desire is for a pattern to apply to only one element or a
       subset of elements, slicing must be used. See [Examples of Patterns](elementdefinition-exampl
      es.html#pattern-examples) for examples of pattern usage and the effect it will have."/>

        A profile on a type can always make mustSupport = true if it is false in the base
       type but cannot make mustSupport = false if it is true in the base type.   This
       is done in [Resource Profiles](profiling.html#mustsupport), where the profile labels
