Data Types

Strings and characters

<when test="type = 'patent'">
...
</when>

Logical Operators

and

<if test="type = 'book' and is_set( creators )">
...
</if>

or

<if test="type = 'book' or type = 'patent'">
...
</if>

not

<if !is_set( creators )">
...
</if>

Comparison Operators

lt

<if test="length(editors) lt 6">
...
</if>

gt

<if test="length(editors) gt 1">
...
</if>

equals

<if test="type = 'patent'">
...
</if>
