In USoft Blend, in contexts where an XPath expression is legal, you can use parenthesised expressions that call one of the following:

A USoft Blend function.

An XPath function.

From a syntax point of view, a call to a USoft Blend function may be recognised by the presence of an explicit namespace prefix as, for example, "dates:" in:

<pc:value-of select="dates:ShowInputFormats" />

 

By contrast, a call to an XPath function may be recognised by the absence of an explicit namespace prefix as, for example, in:

<pc:value-of select="concat( 'A', 'B' )" />
