    This method is called to establish basic signature information for local parameters of a named template, so that this can be checked against xsl:call-template instructions. It is called while a named template is being indexed: see bug 3722.
    
    Throws:
    
    XPathException - if things go wrong
  - getSourceElement
```
public StyleElement getSourceElement()
```

    Returns:
    
    the node in the stylesheet containing this variable binding
  - setVariableQName
```
public void setVariableQName(StructuredQName name)
```
    Set the name of the variable
    
    Parameters:
    
    name - the name of the variable as a QName
  - setDeclaredType
```
public void setDeclaredType(SequenceType declaredType)
```
    Set the declared type of the variable
    
    Parameters:
    
    declaredType - the declared type
  - validate
```
public void validate()
              throws XPathException
```
    Validate the declaration
    
    Throws:
    
    XPathException - if the declaration is invalid
  - postValidate
```
public void postValidate()
                  throws XPathException
```
    Hook to allow additional validation of a parent element immediately after its children have been validated.
    
    Throws:
    
    XPathException - if the declaration is invalid
  - isStatic
```
public boolean isStatic()
```
  - checkAgainstRequiredType
```
public void checkAgainstRequiredType(SequenceType required)
```
    Check the supplied select expression against the required type.
    
    Parameters:
    
    required - The type required by the variable declaration, or in the case of xsl:with-param, the signature of the called template
  - getVariableQName
```
public StructuredQName getVariableQName()
```
    Get the name of the variable
    
    Returns:
    
    the variable's name
  - setProperty
```
public void setProperty(int prop,
                        boolean flag)
```
    Set a boolean property of the variable
    
    Parameters:
    
    prop - the property to be set (e.g. TUNNEL)
    
    flag - true to set the property on, false to set it off
  - hasProperty
```
public boolean hasProperty(int prop)
```
    Get a boolean property of the variable
    
    Parameters:
    
    prop - the property whose value is required
    
    Returns:
    
    true if the variable has the specified property, otherwise false
  - getReferences

```
    Get all the known references to this variable
    
    Returns:
    
    the list of references
  - getSlotManager
```
public SlotManager getSlotManager()
```
    Get the SlotManager associated with this stylesheet construct. The SlotManager contains the information needed to manage the local stack frames used by run-time instances of the code.
