Depending on its parent element, titlegroup can have the following meanings:
| Path | Meaning |
|---|---|
| contentinfo/titlegroup | The title of the book, journal etc. in which the content appears. |
| header/titlegroup | The title of the document e.g. a journal article title. |
| section/titlegroup | A title in a section. |
| tocentry/titlegroup | The title in an entry in a table of contents. |
Below is an example of a journal article title (header/titlegroup). Note the use of attributes to distinguish the main title from its subtitle.

<titlegroup> <title type="document">Activation of pro-astacin</title> <title type="subtitle">Immunological and model peptide studies on the processing of immature astacin, a zinc-endopeptidase from the crayfish <i>Astacus astacus</i></title> </titlegroup>
Note Formatting which applies to the display of the complete article title (for example, if the article title is displayed as italic or bold) should not be captured in the XML file. The following would be incorrect:
<titlegroup> <title type="document"><b>Activation of pro-astacin</b></title> <title type="subtitle"><b>Immunological and model peptide studies on the processing of immature astacin, a zinc-endopeptidase from the crayfish <i>Astacus astacus</i></b></title> </titlegroup>
A surtitle is a heading which appears above a journal article title. Often the tocheading under which an article appears on the journal issue's table of contents is printed as a surtitle in the first article of that category. In the example below, the article on page 444 would be the first article under the "New Perspectives" heading on the issue table of contents.
Occasionally, explanatory text will be associated with a surtitle, and this is specified with a "surtitle_description" attribute.

<titlegroup> <title type="surtitle">New Perspectives </title> <title type="surtitle_description"><i>New Perspectives</i> is intended to allow the communication of comments, viewpoints and speculative interpretation of issues in ecology pertinent to entomology. Comments, viewpoints or suggestions arising from published papers intended to fuel discussion and debate are also welcome. Contributions should be as concise as possible, normally not exceeding two thousand words. Formal research reports will not be acceptable, but summarised novel data, suitably supported by statistics, may be allowed.</title> <title type="document">Monoclonal aphid colonies and the measurement of clonal fitness</title> </titlegroup>
The journal title with which the article is associated (contentinfo/titlegroup). Note the use of attributes to give different versions of the journal title.
<titlegroup> <title type="journal">Molecular Microbiology</title> <title type="abbreviated">Mol Microbiol</title> </titlegroup>
