Alternatives For Processing

Container element used to hold a group of processing alternatives, for example, a single <graphic> that ships in different formats (tif, gif, jpeg) or different resolutions. This element is a physical grouping to contain multiple logically equivalent (substitutable) versions of the same information object. Typically these are processing alternatives and the reader is expected to see only one version of the object.


<alternatives> is not inherently block nor inline in nature, because that is determined by context and usage. Typical examples for this element are a <graphic> that ships with an article in multiple versions (for example, .tif, .jpeg, and SVG-file); or an <inline-formula> that is available as a .tif (<inline-graphic>), encoded in MathML, or encoded in TeX.

Example 1

Alternatives to a table inside <table-wrap>

<sec id="bid.268">
<table-wrap id="bid.269">
<title>Files on the taxonomy FTP site.</title>
<th align="left" valign="top">File</th>
<th align="left" valign="top">Uncompresses to</th>
<th align="left" valign="top">Description</th>
<graphic xlink:href="FAKE-URL.gif"/>

<fn symbol="a" id="mul2">
<p>For non-UNIX users, the file taxdmp.zip includes the
same (zip compressed) data.</p>
<p>Each taxon in the database has a unique identifier,
its taxid. ...</p>

Example 2

Alternatives to an equation, including MathML and a graphic:

<disp-formula id="pbio-0020328-e001">
<mml:math display='block'><mml:mrow><mml:msub>
<graphic xlink:href="pbio.0020328.e001.gif"/>

Example 3
