Examples of org.eclipse.osgi.util.ManifestElement

org.eclipse.osgi.util.ManifestElement
This class represents a single manifest element. A manifest element must consist of a single {@link String} value. The {@link String} value may be split up into component values eachseparated by a semi-colon (';'). A manifest element may optionally have a set of attribute and directive values associated with it. The general syntax of a manifest element is as follows:
```
 ManifestElement ::= component (';' component)* (';' parameter) component ::= ([^;,:="\#x0D#x0A#x00])+ | quoted-string quoted-string::= '"' ( [^"\#x0D#x0A#x00] | '\"'| '\\')* '"' parameter ::= directive | attribute  directive ::= token ':=' argument attribute ::= token '=' argument argument ::= extended  | quoted-string token ::= ( alphanum | '_' | '-' )+  extended ::= ( alphanum | '_' | '-' | '.' )+  
```
For example, the following is an example of a manifest element to the Export-Package header:
```
 org.osgi.framework; specification-version="1.2"; another-attr="examplevalue" 
```
This manifest element has a value of org.osgi.framework and it has two attributes, specification-version and another-attr.

The following manifest element is an example of a manifest element that has multiple components to its value:
```
 code1.jar;code2.jar;code3.jar;attr1=value1;attr2=value2;attr3=value3 
```
This manifest element has a value of code1.jar;code2.jar;code3.jar. This is an example of a multiple component value. This value has three components: code1.jar, code2.jar, and code3.jar.

If components contain delimiter characters (e.g ';', ',' ':' "=") then it must be a quoted string. For example, the following is an example of a manifest element that has multiple components containing delimiter characters:
```
 "component ; 1"; "component , 2"; "component : 3"; attr1=value1; attr2=value2; attr3=value3 
```
This manifest element has a value of "component ; 1"; "component , 2"; "component : 3". This value has three components: "component ; 1", "component , 2", "component : 3".
