             Summary: Why "from" xml element does not support custom attributes in spring xml?
                 Key: CAMEL-11508
                 URL: https://issues.apache.org/jira/browse/CAMEL-11508
             Project: Camel
          Issue Type: Improvement
          Components: camel-spring
    Affects Versions: 2.19.1
            Reporter: Artem St


Hello,

The definition of "from" element in camel-spring.xsd does not allow to use a custom attributes, because of there is no declared anyAttribute element.

There is my route:
        <route id="722b2c5f">
            <from yuo:custom-attr="my custom attribute" uri="localmq://queueStart" />
            <to yuo:custom-attr="my custom attribute" uri="localmq://queue"/>
        </route>

And Camel gives me exception on that route:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 47 in XML document from file [C:\Projects\server\main.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 47; columnNumber: 83; cvc-complex-type.3.2.2: Attribute 'yuo:custom-attr' is not allowed to appear in element 'from'.

My opinion is that "from" element should allow to create user specific attributes same as "to" element (which has a  <xs:anyAttribute namespace="##other" processContents="skip"/>
 in the definition)
