As mentioned previously, the emphasis tag is used to accent certain text. Note that this refers to semantic emphasis and not a typeface. Different stylesheets can render emphasis with different typefaces.

<para id='intro'>
  Gardenias are my absolute <emphasis>favorite</emphasis> flower.  
  Their petals are soft, and their bloom has an absolutely 
  <emphasis>heavenly</emphasis> scent.
</para>     

The term tag is used to mark words or phrases which are being defined. However, its use is confined to either a para or definition tag. The term tag has one optional attribute: src - a URL specifying the source or definition of the term.

<para id='gardenia'>
  <term src="http://en.wikipedia.org/wiki/Gardenia">Gardenias</term> 
  can be tricky to maintain.  The soil around the roots of a 
  <term>gardenia</term> must remain moist always, but too much water 
  can damage the plant.  Also, <term>gardenias</term> enjoy the sun, 
  but if the <emphasis>foliage</emphasis> gets wet to bring the 
  gardenia into the shade.
</para>      

The note tag creates an "out of line" note (which could be a warning, point of interest, etc.) to the reader. The type of note is specified by an optional type attribute. If a type is not specified, the default is Note.

<para id='pollen'>
  Receiving flowers is, on the whole, a wonderful thing.  
  However, sometimes pollen from the flowers can cause 
  problems.  In particular, the clean up of a bit of 
  pollen can be tricky.  <note type="Important">Do not 
  use water when cleaning up pollen!  This can lead to 
  counter-top and clothing stains!</note>  Your best bet 
  is to use a dry method of cleaning with a paper-towel.
</para>      

The cnxn and link tags are used for linking to other documents. The cnxn tag is specifically used for linking to other documents in the Connexions system, while the link tag is used for linking to general documents on the internet.

The cnxn tag has four attributes:

The target and document attributes can be used together or alone. If both are used then you will link to a particular place in another document. If only document is used, you will link to a document as a whole. If only target is used, you will link to a particular tag within the current document.

The strength attribute is optional and can give the reader an indication of how related the additional information is to the current discussion.

Example 4: CNXN Example

The cnxn tag does not have to have a description of the destination in order to be used. For example, say you want to link to a figure. You could you use a cnxn similar to the one below:

    <cnxn target='tbonefig' document="m10278"/>

The above markup will display as:

(Reference)

Notice how the display says "(Reference)". When you point to something that it not within the document, this will be the display. However, pointing to a tag within the document has a different display:

    <cnxn target="element-852"/>

Figure 1

Using an empty cnxn tag like this is an easy way to point to a specific part of a document; all the numbering is done for you, and if you need to insert a new figure in the middle of the document, the numbering will change automatically.

<cnxn target='element-852'>Momosa Picture</cnxn>

The link tag, on the other hand, has only a required src tag which contains a URL for the target online document.

<para id='moretips'>
  For more gardening tips, see 
  <link src="http://www.bhg.com/bhg/gardening/index.jhtml">Better 
  Homes and Gardens' Garden Section</link>.  
</para>   

The cite tag is used to refer to non-electronic materials within a document, and primarily contains the title, the author, and/or a page number of a work.

Finally, a good resource is the <cite>Garden Lover's 
Cookbook -- William M. Rice; Paperback</cite>.

The quote tag is used to denote that some text directly quotes another source. The quote tag has a type attribute which denotes whether the quote is inline or block.

<para id='steakquote'>
  Every plant needs a different amount of water in order to grow 
  well. <quote>"If you water each plant the same, you will always 
  water too much and too little."</quote>  Also, remember the words 
  of Lou Erickson: 
  <quote type='block'>"Gardening requires lots of water - most of 
  it in the form of perspiration."</quote>
</para>

The foreign tag is used to denote that a word or phrase foreign to the language of the document is being used.

<para id='steakquote2'>
  All flowers have a scientific name, often derived from latin.  
  <foreign>Gardenia augusta</foreign> is the name of a type of 
  gardenia found in Japan.
</para>

The code tag is used to insert example computer output/input as either inline text within a paragraph or as a block of text. The code tag has a type attribute with two possible values:

<para id='copy'>
  In a unix terminal the command to copy a file is 
  <code type='inline'>cp original copy</code>.
</para>
