Overview

About this proposal

An XVCL processor must imply the type of a variable. The value of a variable is set with the value attribute of the set tag.

Example

 <set var="version" value="1a"/>

Unfortunately for my application, the XVCL processor interprets "1a" as the number "1".

Proposal

Interpret "1a" as a string, not a number, because it contains the letter "a".

 <set var="version" value="1a"/>

Or, support an explicit type using a type attribute.

 <set var="version" value="1a" type="string"/>

How do I?

 <set var="package" expr="?@package.prefix??@version?"/>
 <set var="directory" expr="?@directory.prefix??@version?"/>
 <set var="classname" expr="?@x-frame.name?"/>
 <set var="directory" expr="?@x-frame.outdir?"/>
 <set var="package" expr="?fn("pd2pn",@x-frame.outdir)?"/>
