       a client, it means the system will search by this profile and process data according to
       the guidance implicit in the profile."/>
      <comments value="Supported profiles are different to the profiles that apply to a particular resource in
       rest.resource.profile. The resource profile is a general statement of what features of
       the resource are supported overall by the system - the sum total of the facilities it
       supports. A supported profile is a deeper statement about the functionality of the data
       and services provided by the server (or used by the client). A typical case is a laboratory
       system that produces a set of different reports- this is the list of types of data that
       it publishes. A key aspect of declaring profiles here is the question of how the client
       converts knowledge that the server publishes this data into working with the data; the
       client can inspect individual resources to determine whether they conform to a particular
       profile, but how does it find the ones that does? It does so by searching using the _profile
       parameter, so any resources listed here must be valid values for the _profile resource
       (using the identifier in the target profile).  Typical supported profiles cross resource
       types to describe a network of related resources, so they are listed here rather than
       by resource. However they do not need to describe more than one resource."/>

       a client, it means the system will search by this profile and process data according to
       the guidance implicit in the profile."/>
      <comments value="Supported profiles are different to the profiles that apply to a particular resource in
       rest.resource.profile. The resource profile is a general statement of what features of
       the resource are supported overall by the system - the sum total of the facilities it
       supports. A supported profile is a deeper statement about the functionality of the data
       and services provided by the server (or used by the client). A typical case is a laboratory
       system that produces a set of different reports- this is the list of types of data that
       it publishes. A key aspect of declaring profiles here is the question of how the client
       converts knowledge that the server publishes this data into working with the data; the
       client can inspect individual resources to determine whether they conform to a particular
       profile, but how does it find the ones that does? It does so by searching using the _profile
       parameter, so any resources listed here must be valid values for the _profile resource
       (using the identifier in the target profile).  Typical supported profiles cross resource
       types to describe a network of related resources, so they are listed here rather than
       by resource. However they do not need to describe more than one resource."/>
