${content_refs} - References to Content Chunks

Content chunks and variables can be referred to using this format. This is evaluated before any other variable reference is.

${name}

Content chunks can refer to other chunks, URLs, or use deferred references, up to 30 levels deep.

If you wish to refer to a content item or variable, but are not sure if it exists, you can provide a default value by following the content name with a question mark and the default value.

${name?defaultvalue}

Content references can also be parameterised references; this means that they act like function calls, in a way, allowing you to pass in parameters. They look like this:

${name: parameter="value" ...}

The parameters are declared in the XML style.

Note: the parameters' values must not contain further content references, due to a limitation in the way WebMake parses content refs. If you want to refer to a content item from within a template, pass in the name of the content item, and get the template to expand it; see the example below.

For example, if you set up a template item like this:

	<template name="mytemplate">
		You passed in ${name}, and its value is \"${${name}}\".
	</template>

and a content item like this:

	<content name="foo">
		Hi, I'm foo!
	</content>

Then a reference to:

${mytemplate: name="foo"}

will expand to:

**You passed in foo, and its value is \"Hi, I'm foo!\".
