  </header>

  <p>Inline tags are typically used within block tags, for example to
    highlight a word within a paragraph.</p>

  <section>
    <marker id="brTAG"></marker>
    <title>&lt;br&gt; - Line Break</title>

    <p>Forces a newline. The <c><![CDATA[<br>]]></c> tag is both a
      block- and an inline tag and is described in
      the <seeguide marker="block_tags#brTAG">Block Tags</seeguide>
      section.</p>
  </section>

  <section>
    <marker id="cTAG"></marker>
    <title>&lt;c&gt; - Code</title>

    <p>Highlights things like variables and file names in a text flow.
      Can contain plain text only. Newlines and tabs are ignored as
      opposed to the <seeguide marker="block_tags#codeTAG">code</seeguide>
      tag. All <seeguide marker="character_entities">character
	entities</seeguide> are expanded. Example:</p>
    <pre>
&lt;p>Returns &lt;c>true&lt;/c> if &lt;c>Term&lt;/c> is an integer.&lt;/p>
    </pre>
    <p>results in:</p>
    <p>Returns <c>true</c> if <c>Term</c> is an integer.</p>
  </section>

  <section>
    <marker id="emTAG"></marker>
    <title>&lt;em&gt; - Emphasis</title>

    <p>Highlights words which are important within a text flow. Example:
    </p>
    <pre>
&lt;p>The application &lt;em>must&lt;/em> be up and running.&lt;/p>
    </pre>
    <p>results in:</p>
    <p>The application <em>must</em> be up and running.</p>

    <p>Contains plain text or a
      <seeguide marker="#cTAG">&lt;c&gt;</seeguide> tag.</p>
  </section>

  <section>
    <marker id="markerTAG"/>
    <title>&lt;marker&gt; - Marker</title>

    <p>Used as an anchor for hypertext references. The <c>id</c>
      attribute defines the name of the marker. Example:</p>
    <marker id="marker_example"/>
    <pre>
&lt;marker id="marker_example"/&gt;
    </pre>
  
    <p>The <seeguide marker="#seeTAG">&lt;see*&gt;</seeguide> tags
      are used to refer to the marker.</p>

    <p>The <c><![CDATA[<marker>]]></c> tag is both a block- and an
      inline tag.</p>
  </section>

  <section>
    <marker id="seeTAG"/>
    <title>&lt;see*&gt; - See tags</title>
    <p>A cross reference (hypertext link) to a marker in the same file,
      a marker in another file, or (the top of) another file, given by
      the <c>marker</c> attribute. The syntax used within the <c>marker</c>
      attribute is <c>application:file#anchor</c> for the general case.
      <c>application</c> and <c>file</c> can be omitted if the link target
      is the current application or file.</p>
    <p>There are several different see tags that are to be used depending on
      what it is that they point to.</p>
    <taglist>
      <tag>&lt;seemfa&gt;</tag>
      <item>
        <p>Points to an MFA using the syntax <c>application:module#function/arity</c>.
        These links must point to functions documented in a &lt;funcs&gt; section.
          Examples:</p>
        <pre><![CDATA[
<seemfa marker="stdlib:string#length/1">string:length/1</seemfa>
<seemfa marker="string#length/1">string:length/1</seemfa>
<seemfa marker="#length/1">string:length/1</seemfa>
]]></pre>
        results in: <seemfa marker="stdlib:string#length/1">string:length/1</seemfa>.
      </item>
      <tag>&lt;seeerl&gt;</tag>
      <item>
        <p>Points to an Erlang module or a custom <seeguide marker="#markerTAG">marker</seeguide>
          within a module. Example:</p>
        <pre><![CDATA[
<seeerl marker="stdlib:string">string(3)</seemfa>,
<seeerl marker="stdlib:string#oldapi">Old API in string</seemfa>
]]></pre>
        results in: <seeerl marker="stdlib:string">string(3)</seeerl>,<seeerl marker="stdlib:string#oldapi">Old API in string</seeerl>.
      </item>
      <tag>&lt;seetype&gt;</tag>
      <item>
        <p>Points to a type using the syntax <c>application:module#type</c>.
        These links must point to types documented in a &lt;datatypes&gt; section.
        Example:</p>
        <pre><![CDATA[
<seetype marker="stdlib:string#grapheme_cluster">string::grapheme_cluster()</seetype>
]]></pre>
        results in: <seetype marker="stdlib:string#grapheme_cluster">string::grapheme_cluster()</seetype>.
      </item>
      <tag>&lt;seeapp&gt;</tag>
      <item><p>Points to the application documentation. <c>index</c> can be used as the target file.
        Example:</p>
        <pre><![CDATA[
<seeapp marker="stdlib:STDLIB_app">STDLIB app</seeapp>,
<seeapp marker="stdlib:index">STDLIB index</seeapp>
]]></pre>
        results in: <seeapp marker="stdlib:STDLIB_app">STDLIB</seeapp>, <seeapp marker="stdlib:index">STDLIB</seeapp>.
      </item>
      <tag>&lt;seecom&gt;</tag>
      <item>

      </item>
      <tag>&lt;seecref&gt;</tag>
      <item>
        <p>Points to the documentation of any C reference. Example:</p>
      <pre><![CDATA[
<seecref marker="erts:erl_nif">erl_nif</seecref>
]]></pre>
        results in: <seecref marker="erts:erl_nif">erl_nif</seecref>.
      </item>
      <tag>&lt;seefile&gt;</tag>
      <item>
        <p>Points to the documentation of a file format. Example:</p>
        <pre><![CDATA[
<seefile marker="kernel:config">config(3)</seefile>
]]></pre>
        results in: <seefile marker="kernel:config">config(3)</seefile>.
      </item>
      <tag>&lt;seeguide&gt;</tag>
      <item>

          <c>index</c> can be used as the target file. Example:</p>
          <pre><![CDATA[
<seeguide marker="kernel:index">Kernel User's Guide Index</seeguide>,
<seeguide marker="kernel:logger_chapter">Logging in the Kernel User's Guide</seeguide>
