   <GeneralSection>
      <Paragraph>Error signals are item
		signals that indicate errors occurring during a planning run.</Paragraph>
      <Paragraph>Some errors are
		relatively easy to solve, for example, by supplying a default value or
		parameter where LN expects one. In other cases, however, the error can be of a more serious
		nature, and can lead to failure of the planning as a whole.</Paragraph>
      <GeneralSection>
         <SectionTitle>Fatal Error</SectionTitle>
         <List>
            <ListIntro>A fatal error occurred. A message is given to specify the
			 fatal error. Examples of a fatal error:</ListIntro>
            <ListItem>The program is running
			 out of memory.</ListItem>
            <ListItem>An internal sort
			 failed.</ListItem>
         </List>
         <Paragraph>In most cases the
		  session that started the signal generation will be aborted. If any planning has
		  been generated, it can probably not be trusted.</Paragraph>
         <Paragraph>This signal is not
		  related to a specific item.</Paragraph>
