java.lang.Object
- net.sf.saxon.style.AttributeValueTemplate

```
public abstract class AttributeValueTemplate
extends java.lang.Object
```
This class represents an attribute value template. The class allows an AVT to be parsed, and can construct an Expression that returns the effective value of the AVT.
This is an abstract class that is never instantiated, it contains static methods only.

```
public static Expression make(java.lang.String avt,
                              StaticContext env)
                       throws XPathException
```
    Static factory method to create an AVT from an XSLT string representation. The method is also used for text value templates.
    
    Parameters:
    
    avt - the attribute value template (or TVT) as written.
    
    env - the static context
    
    Returns:
    
    an expression that computes the value of the attribute / content, as a string. In the case of a TVT this must be further processed to create a text node.
    
    Throws:
    
    XPathException - if a static error is found
  - makeFirstItem
```
public static Expression makeFirstItem(Expression exp,
                                       StaticContext env)
```
    Make an expression that extracts the first item of a sequence, after atomization
    
    Parameters:
    
    exp - an expression that evaluates to a sequence
    
    env - the static context of the expression
    
    Returns:
    
    an expression that returns the first item in the sequence returned by exp
