904

905
|

|
* Paperg: Add the colon to the attribute, so that it properly finds |

|
* <tag attr:ibute="something" > like google does. |
|
907

|
910
|

|
* |
|

|
912
|
|
|
* implies that an attribute can begin with an @ sign that is not |
|
913
|
|
|
* captured. This implies that an html attribute specifier may start |
|
914
|
|
|
