I have an xml file (see below) and created a schema (see below) in order to generate the type tree. When trying to create map rules, I cannot figure out how to populate the "parameter" tag. I can populate the "name" attribute for the parameter tag without an issue, but any time I try to enter a rule that evaluates to the value I want populated in the "parameter" tag, I just get a build error like the one below.

Map: HL7_in Output: parameter [1]:method:hsp_canonicalgrammar_request Element:Global:output1
Output argument of rule does not match output type: ="sampleText"

I understand the fact that the "parameter" tag is defined as a Group Class in the type tree and that I am getting this error because I cannot simply assign a text value to "parameter" since WTX is expecting the rule for "parameter" to evaluate to a "paramater" object as opposed to a string. But I need to assign a string value as indicated in the sample XML below, and I cannot figure out anyway to do it. Any help would be greatly appreciated.

SAMPLE XML
<?xml version="1.0" encoding="UTF-8"?>

<hsp_canonicalgrammar_request>

<PurposeForUse>TREATMENT</PurposeForUse>
</header>

<method name="findSubjectsByDemographics">

<parameter name="lname">Franklin</parameter>
<parameter name="mname" />
<parameter name="suffix" />

<parameter name="gender">F</parameter>
</method>

</hsp_canonicalgrammar_request>

You didn't mention the WTX version, or whether you selected "Xerces" or "Classic" validation when you were importing the schema to build the type tree. I created a type tree and simple map using "Xerces" validation and it produced the group and items names shown below.

Are you trying to enter your rule on a "parameter" line or on a "Value parameterType Type" line?

You should be entering a rule on a "Value parameterType Type" line which is defined as an item. Here should be able to enter a straight text string value or some type of rule that results in a text string.
